Браузер Форекс, Опера

Opera and Mozilla Firefox both predate the Google Chrome browser and remain widely used to this day. Even as Chrome has taken over the web browser market, these senior browsers have adapted to modern browser trends to stay in the game. In this Opera vs Firefox comparison, we&#;ll take a look at which one is the better Chrome alternative.

Key Takeaways:

• Opera is designed to make extensions unnecessary by including a full range of built-in features
• Firefox has an excellent privacy policy, while Opera’s privacy protections are less reliable
• Opera is faster than Firefox, but not as fast as Chrome
• Unlike most other browsers, Firefox uses its own browser engine instead of Chromium

Mozilla Firefox was one of the most dominant browsers during the pre-Chrome era of the internet alongside Internet Explorer, and is currently the most popular alternative to Chrome. Opera established itself as a more specialized browser by offering built-in features usually left for extensions or separate software applications.

We&#;ll focus our attention on the major differences between Opera and Firefox, so if you want a complete review of each, feel free to read our Opera review and our Firefox review.

Opera vs Firefox: Rounds & Criteria

Our verdict will be determined by each browsers&#; offerings in the following five categories: features, ease of use, performance, security and privacy. One browser will be the winner in each of these categories, earning a point for each round, and the first browser to reach three points will be declared the overall winner.

1. Features

A good browser should have more capabilities than just accessing the internet. We&#;ll take a look at basic browser tools, like cross-device synchronization, extension libraries, communication apps and much more.

Opera Features

The Opera browser was designed for built-in features. It originally came to prominence because of its built-in email client and other unique features. Although that feature was taken out long ago, Opera has continued to integrate enough built-in tools to reduce the need for extensions.

In lieu of its old built-in email client, Opera has since added a number of messaging apps to the browser. These include Instagram, Facebook Messenger, WhatsApp, Twitter, Telegram and V Kontakte. These shortcuts make the Opera browser an all-in-one communications app while reducing the inconvenience of switching between separate applications.

Opera&#;s cross-device sync is excellent as well. You&#;ll find the &#;My Flow&#; feature on the sidebar, which allows you to unify your browser data across multiple devices. Synced browser data includes your bookmarks, browsing history and settings. You can even send encrypted files across devices.

Using My Flow doesn’t require signing into your Opera account &#; just scan a QR code and your files will travel from one device to another. Going without an account is fast and convenient, but you won’t get the full spectrum of tools Opera offers without logging in.

Following Google Chrome&#;s rise to prominence, Opera became one of the first browsers to adopt the Chromium engine after Chrome itself. This means users can access Google’s vast library of Chrome extensions in case Opera&#;s out-of-the-box tool set isn&#;t enough. Opera also runs its own add-ons library.

Firefox Features

The Firefox browser may not have the same range as Opera, but it comes with enough capabilities for a convenient browsing experience. Firefox includes essential features like device sync, a reader view and even a news reader.

In a world where Chromium-based browsers are the status quo, Firefox is one of the few to use its own browser engine. That means it isn&#;t compatible with the largest extensions library in the world, but it still operates an extensive library of add-ons that should have more than enough tools for most users.

The Opera browser is the clear winner for this round. Opera has built its reputation as the Swiss army knife of browsers, while Firefox has only a basic set of in-browser capabilities and is not compatible with Chromium extensions.

2. Ease of Use

In this round, we&#;ll assess how convenient it is to browse the web with Opera and Firefox. Ease of use takes into account traits such as interface design and navigation.

Opera’s Ease of Use

Opera&#;s interface is easy to use but slightly different from the minimalist Chromium design. The sidebar is the most obvious addition to Opera not found in Firefox or Chrome, and it’s where you will find the communication apps, My Flow and workspaces.

Opera&#;s workspaces lie somewhere between tabs and windows. Buttons on the sidebar lead to different workspaces, which will display separate interfaces for different groups of tabs. 

With this feature, you can keep different groups of tabs separate instead of opening a new window, which comes in handy if you want to separate your personal browser use from your professional purposes.

The first page you see when launching Opera is its default “speed dial” page. This page contains a list of links for some of the most popular websites on the web including Amazon, Walmart and others. You can customize this page with links to your most frequently visited sites.

Tabs in Opera shrink in size instead of scrolling. This can be irritating when you have a large number of tabs open and the webpage headings aren&#;t displayed fully, but the &#;search tabs&#; button opens an easy-to-read list of all open tabs.

Firefox’s Ease of Use

There isn&#;t much to say about Firefox&#;s interface aside from its simplicity. It has the same clean interface as any other web browser, featuring a tab bar, bookmark bar, an address/search bar at the top, a few buttons off to the side and the webpage itself. We have a guide on how to backup Firefox&#;s bookmarks.

Opening a large number of tabs enables horizontal scrolling rather than shrinking, and a dropdown menu provides a list of all open tabs.

Opera wins once again. Both are simple and easy to use, but Opera&#;s wider range of tools keeps things more streamlined than in Firefox.

3. Performance

No one wants to use a slow browser even if it&#;s full of convenient features. We tested Opera and Firefox for their speed and resource consumption. The three browser speed tests we used are Speedometer, JetStream 2 and MotionMark. 

Speedometer is the most important test because it gives the most comprehensive assessment of their overall speed. JetStream 2 calculates the browser&#;s speed when processing unusual and advanced applications, and MotionMark tests the browser&#;s ability to render visuals.

Both browsers are fast, but some other browsers are even faster &#; namely, Chrome and Microsoft Edge. You can see a full breakdown of our browser speed tests in our fastest browser article.

Opera consistently defeated Firefox in each of the three tests, even though Firefox isn&#;t a slow browser by any means. Both have a high rate of RAM consumption, though. Chrome consumes less RAM than Firefox and Opera on average, although the Chromium engine has improved its RAM consumption since a March update.

Since Firefox is a bit slower than Opera, we&#;ll give Opera the victory in this round. This makes Opera the overall winner, but with two more rounds to go, we&#;ll still finish the competition and see if Firefox can redeem itself.

4. Security

For the security round we&#;ll see how each browser protects its users from external threats like phishing and malware. Safe browsing databases, update frequency and insecure connection warnings are the main security features to look out for.

Opera doesn&#;t use the Google Safe Browsing database to protect its users against malicious websites even though it runs on Chromium. Instead, the browser developers have equipped Opera with the less effective PhishTank and Yandex Safe Browsing databases.

Though not a Chromium browser, Firefox uses Google Safe Browsing. It&#;s Google&#;s database of known malicious websites that will prevent users from navigating to those pages.

The good news is that Opera stays a step ahead of malicious ads with its built-in ad blocker and pop-up blocker. Firefox blocks pop-ups but lacks an ad blocker. Fortunately, you can easily download one of the best ad blocker extensions.

Updates & Alerts

Both browsers benefit from a regular update schedule. The Opera team usually issues security updates every week, and sometimes multiple times a week. Firefox is likewise punctual in patching security holes before cybercriminals have a chance to exploit them.

Firefox and Opera both alert users when connecting to a website over an unsecure HTTP connection. Opera displays a warning symbol in the address bar along with the caption &#;not secure,&#; while Firefox only shows the symbol. It&#;s a small thing, but Opera is marginally better about alerting its users to insecure connections than Firefox.

Firefox scores its first point in this round by making use of Google Safe Browsing. Even though Firefox lacks a built-in ad blocker like Opera, you can easily block ads with an extension while staying protected by Google Safe Browsing. Opera is not quite as safe overall due to its less reliable safe browsing solutions.

Firefox has better security than Opera, but it’s not the most secure web browser we’ve ever reviewed. Check out our most secure browser article for alternatives if security is your top priority.

5. Privacy

A good browser will protect your personal data from everyone you don&#;t want to share it with, including the browser developer itself. In our final round, we&#;ll see how well each browser protects your personal data from prying eyes.

A shade of doubt has been cast over Opera&#;s trustworthiness since That was the year that the Chinese app developer Qihoo acquired Opera, thus placing Opera within the jurisdiction of the Chinese government. 

The privacy of Opera users looks questionable given the Chinese government&#;s track record of surveillance and power over Chinese technology corporations.

Furthermore, Opera&#;s privacy policy makes it clear that Opera collects data on its users and reserves the right to share it with third parties, such as app developers partnering with the browser company.

We like that Opera includes a built-in VPN, but it’s very limited. There is no information about the number of servers, the type of encryption used or the servers’ location beyond three broad regions &#; Asia, Europe and the Americas &#; making it useless for removing geoblocks. 

It’s a great feature in theory, but Opera’s VPN needs work. If a VPN is what you need, consider a dedicated service like ExpressVPN or a trustworthy, free VPN like Windscribe instead.

Firefox Privacy

Meanwhile, Firefox is far more respectful of its users&#; personal data. Mozilla is a nonprofit company that doesn&#;t make its money by collecting and selling user data for targeted advertising. The Mozilla privacy policy clearly states that the Firefox browser collects a minimal amount of data for development purposes.

Collected data is associated with a randomized identifier rather than your name or email address. Mozilla collects interaction data about the way you use the browser rather than collecting personally identifiable information. This shouldn’t compromise your privacy, but Firefox still provides the option to opt out of some kinds of data collection.

Firefox includes enhanced tracking protection that lets you decide what kinds of trackers or cookies you want to block. These privacy features come with two levels of intensity, standard and strict, in addition to a custom setting.

The standard mode for the tracking controls blocks some third-party tracking cookies, fingerprinters, crypto-mining scripts and social media trackers. The strict mode blocks all tracking content and may cause some websites to break or malfunction.

Private Browsing

Firefox and Opera both have a private browsing mode feature. Both are more or less the same, allowing you to browse without risking the exposure of your browsing data or cookies.

Keep in mind that private browsing modes don’t shield your identity from your ISP or snooping third parties on the web. VPNs are a better privacy tool, which you can read about in our VPN guide.

Firefox wins the final round by a long shot, bringing the final score to Even though Firefox lost, it picked itself up in the last two rounds with its reliable security and privacy protections. Take a look at our anonymous browsing guide for more tips on how to cover your tracks on the internet.

The Verdict

Opera wins for its wide array of built-in tools, its ease of use and fast speed. However, Firefox picked up the pace at the end due to its superior security and privacy protections. It&#;s one of the best browsers for Mac, just in case you&#;re looking for a browser for your Apple device.

Even though Opera is the official winner of this comparison, your personal preferences will play a bigger role in determining whether to use a feature-rich browser or a more secure one.

In today's fast-paced world, speed is of the essence. When it comes to browsing the web, users want a fast and efficient experience that allows them to quickly access the information they need. Two popular web browsers, Opera and Mozilla Firefox, are known for their speed and performance. Let's take a closer look at what makes these browsers stand out.

Opera's Turbo Mode and Speed Dial

Opera is a browser that has been designed with speed in mind. One of its key features is Turbo Mode, which allows users to browse the web faster by compressing data and reducing page load times. This is particularly useful for users who have slow internet connections or are browsing on mobile devices. With Turbo Mode, users can enjoy a faster browsing experience, even when their internet connection is less than ideal.

Another feature that makes Opera stand out is Speed Dial. This is a customizable feature that allows users to quickly access frequently visited websites. Users can add their favorite websites to Speed Dial and arrange them in any order they like. This means that they can access their favorite websites with just a few clicks, without having to type in the URL every time.

Opera's performance is further enhanced by its built-in ad blocker and malware protection features. These features help to keep users safe while they browse the web, by blocking ads and preventing malicious software from being downloaded onto their devices.

Mozilla Firefox's Quantum Engine

Mozilla Firefox is another browser that is known for its speed and performance. Its latest version, Firefox Quantum, features a new engine that has been designed to provide users with a fast and efficient browsing experience. The engine uses multiple processor cores to speed up page rendering and offers improved memory management to reduce browser crashes.

Firefox Quantum also features built-in tracking protection and ad blocking features. This means that users can browse the web without being tracked by advertisers or having to deal with annoying ads. These features not only contribute to Firefox's speed and performance but also to its overall security.

In conclusion, both Opera and Mozilla Firefox are excellent choices for users who are looking for a fast and efficient browsing experience. Whether you choose Opera's Turbo Mode and Speed Dial or Firefox Quantum's new engine and built-in tracking protection, you can be sure that you are getting a browser that is designed with speed and performance in mind.

Security and Privacy Features

With the increasing amount of sensitive information being shared online, it is essential to have a browser that prioritizes security and privacy. In this regard, Opera and Mozilla Firefox are two of the most popular browsers that offer advanced security and privacy features.

Opera's Built-in VPN and Ad Blocker

Opera's built-in VPN is one of its most notable features. It allows users to encrypt their internet traffic and route it through a remote server, providing an added layer of security. This feature is particularly useful for those who frequently use public Wi-Fi networks, which are often unsecured and vulnerable to cyber attacks.

In addition to its VPN, Opera also has an ad blocker that prevents unwanted ads from appearing on webpages. This not only improves the user experience but also reduces the risk of malware infections. Ads are a common way for cybercriminals to distribute malware, and by blocking them, Opera helps users stay safe online.

Opera's security and privacy features don't end there. The browser also has a built-in fraud and malware protection system that warns users of potentially harmful websites. This feature is particularly useful for those who are not well-versed in online security and may be more susceptible to phishing scams and other cyber threats.

Mozilla Firefox's Enhanced Tracking Protection

One of Mozilla Firefox's most notable security features is its enhanced tracking protection. This feature blocks third-party cookies, which are often used to track users' online activities across multiple websites. By blocking these cookies, Mozilla Firefox helps protect users' personal data and privacy online.

Firefox's privacy mode is another feature that prioritizes user privacy. When enabled, it ensures that online activities are not recorded in the browser history or any other location on the computer. This is particularly useful for those who share a computer with others and want to keep their online activities private.

Firefox's security features are further enhanced by its ability to detect and block phishing attempts. Phishing is a common tactic used by cybercriminals to steal sensitive information, such as usernames and passwords. By detecting and blocking these attempts, Firefox helps keep users' personal information safe.

Finally, Firefox also has a built-in download protection system that warns users of potentially harmful downloads. This feature is particularly useful for those who frequently download files from the internet and want to ensure that they are safe and secure.

In conclusion, both Opera and Mozilla Firefox offer advanced security and privacy features that help users stay safe online. Whether you're using a public Wi-Fi network or simply browsing the internet from home, these browsers prioritize your security and privacy, giving you peace of mind while you surf the web.

Extensions and Add-ons

Extensions and add-ons are powerful tools that can enhance your browsing experience by providing additional functionality and customization options. In this article, we will take a closer look at two popular browsers, Opera and Mozilla Firefox, and their extension libraries.

Opera's Extension Library

Opera's extension library is a diverse collection of add-ons that can be used to customize and enhance the browser's functionality. Whether you're looking for a password manager, note-taking tool, or social media integration, Opera's extension library has got you covered.

One popular extension in Opera's library is the "LastPass" password manager. This extension securely stores all of your passwords and allows you to log in to your favorite websites with just one click.

Mozilla Firefox's Massive Add-on Collection

Mozilla Firefox's add-on collection is one of the largest and most diverse available on any browser. With over 35, add-ons to choose from, there's no shortage of options when it comes to customizing your browsing experience.

One popular add-on in Mozilla Firefox's collection is "Adblock Plus," which blocks annoying ads and pop-ups from appearing on your screen. Another useful add-on is "Ghostery," which protects your privacy by blocking trackers and analytics scripts from websites.

But Mozilla Firefox's add-ons aren't just about blocking unwanted content. There are also plenty of add-ons that can help you be more productive, such as "Pocket," which lets you save articles and web pages to read later, and "Copy Link Text," which allows you to copy the text of a link without copying the entire URL.

In conclusion, both Opera and Mozilla Firefox offer a wide range of extensions and add-ons that can enhance your browsing experience. Whether you're looking for productivity boosters, privacy tools, or just some fun add-ons, there's something for everyone in these two popular browsers.

Conclusion: Which Browser is Right for You?

Both Opera and Mozilla Firefox are strong choices for web browsing, offering a range of features and capabilities for users. Whether you prioritize speed, security, or customization, each browser has unique strengths and weaknesses. Ultimately, the decision of which browser to use will depend on your personal preferences and needs. Consider your usage patterns and take the time to explore the features and functionality of each browser before making a decision.

The Mozilla Firefox and Opera browser are both privacy-centric browsers.

But when it comes to Opera vs. Firefox, Opera offers many rich features like VPN service, social connectivity panel, AI integration, anonymous registration for sync, etc.

It is unique to the Opera browser and is preferred over Firefox.

Support for Blocking the Online Trackers

Our Winner: Mozilla Firefox

Trackers constantly monitor your online browsing activity when surfing the World Wide Web. While the benefit for the same is documented to help the browser send curated content to the user, there&#;s much more to that since they possess a significant security risk.

In this regard, Opera seems to have quite a decent job. They have blocked all the third-party tracking cookies by default, so you have one less thing to worry about. Not only that, but they have also incorporated tracker-blockers that are known to block all the crypto-mining scripts, which is something that not many other browsers could claim.

However, Mozilla has taken this even a step ahead. Rather than directly blocking all the trackers, it has segregated its tracker-blocking mechanism into Standard, Strict, and Custom segments. Apart from that, it also blocks all the social media trackers, which has become the need of the hour.

So while both browsers seem to have given attention to the tracker blocking, Firefox takes the upper hand, mainly because it gives users more granular controls over this functionality.

Misleading Ad Blockers Support

Our Winner: Opera browser

The sites that tend to adopt the practice of sending intrusive and disruptive ads are always on the rise. All this tends to disrupt the standard workflow of the users apart from breaking down the UX/UI element. This is where the need for an ad-blocker arises.

Keeping a note of the same, Opera comes equipped with a built-in ad blocker. And it performs decently well. Not only can it stop all the different ad layouts, but it also allows you to create your own rules. For example, you may add your preferred sites to the allowlist, so the latter could still display ads and earn their fair share of revenues.

However, there&#;s no such thing as an ad-blocker regarding Mozilla&#;s offering. So there are two different approaches that you could opt for. These include installing third-party add-ons or going for the Strict level of tracking block, blocking most intrusive ads.

A native ad blocker is always a good option rather than depending on an add-on or an indirect approach of blocking trackers to stop the ads. So Opera manages to outdo Firefox in this domain.

Anonymity and VPN Support

Our Winner: Opera browser

VPN provides a safe and encrypted passage for data transfer from the source to the destination. Apart from that, it also allows you to access geo-restricted content with ease.

In this regard, Opera has again taken a similar route and has built in a VPN tool. With just a single click, you could enable it and browse via the location of your choice. Likewise, it also displays some additional information sets, such as the total data exchanged and its date and time. You could even use this VPN in Private Browsing mode.

Related: How to Use VPN for Browsing from Different Country or Regions

If we focus on Firefox, there&#;s no built-in Virtual Private Network. As a result, you would again have to be on the lookout for a decent VPN app or extension.

While Opera&#;s VPN is still far from a finished product, its presence in its ecosystem by default makes the job easier for the end-user. As a result, it takes the upper hand over Firefox in the battle of VPNs!

Data Sync and Cross-Device Support

Our Winner: Opera browser

Having cross-device support has now become a necessity rather than a luxury. Syncing all your data and allowing you to access your contents from all the linked devices streamlines all our workflow data.

Once you sign in with your Opera account, your bookmarks, history passwords, and saved data are easily accessible across all the linked devices. Then its My Flow features prove to be the icing on the cake. You could easily share different file types without logging into your account, including images, videos, links, and notes.

Firefox also allows you to sync browser data across different devices. Sign in via your account, and then you can access bookmarks, settings, data, and opened tabs between all these devices.

While both browsers have a decent cross-device support system, Opera&#;s My Flow feature easily edges out its competitor.

Secondary Utility Tools within Browser

Our Winner: Tie!

Nowadays, every browser comes preloaded with some handy utility tools. They help the end-users and help the browser create its unique identity.

In this regard, Opera has baked in quite a lot of add-ons. To begin with, you could easily take screenshots on the go, use Spell Checking to check for spelling and grammatical mistakes, enable Reader Mode for a distraction-free environment, or even give a shot at its Unit Converters. Likewise, it also comes with a built-in CryptoCurrency Wallet.

The Mozilla Firefox browser also presents Spell Check, Reader Mode, and Screenshot Editor. Furthermore, it has also added a Bookmark Manager to handle all your bookmarks across the synced devices effectively. Moreover, using its Picture in Picture Mode, you could watch your preferred videos in a small overlay window that could be resized and dragged to any corner of your screen.

Compared to Firefox, Opera doesn&#;t have a Text Speech or AutoPlay Blocking feature. On the flip side, Firefox misses out on Battery Saver and Workspaces that Opera could brag about. In this section, handling a winner&#;s medal ultimately boils down to individual preferences.

Built-in Customizations Offering

Our Winner: Mozilla Firefox

Many users prefer to change the look and feel of the stock browsing experience. There&#;s much to try, from tweaking the user interface to modifying individual browser components.

Opera has always been known to be among the most customizable browsers, and there are quite a few reasons to justify this claim. From changing the themes to switching over different wallpaper or even accessing your social media and instant messaging handles, all this is just a click away. Likewise, you could customize the news-reader with the topic of your interest.

Firefox also displays news feeds and articles directly from Pockets. Likewise, it allows you to tweak the Title bar, Menu bar, and Bookmarks toolbar. Apart from that, you could also download additional themes from the store.

Again, it&#;s hard to tag a clear-cut winner in this domain. While Opera allows you to customize the entire interface, Firefox focuses on tweaking individual browser components.

Third-party Extensions and Add-on Support

Our Winner: Opera browser

Extensions are third-party add-ons that tend to add more features to the browser. While some focus on utility, others promise a much safer browsing experience, and some are a boon for the official workspaces.

Opera boasts of a plentitude of extensions spread across varied domains. There&#;s much to look forward to, from Adblockers to password managers to social media and tabs management. While the UI of its extension store looks a tad outdated, that shouldn&#;t cause any significant issues as its categories and filer tabs will make it relatively easy to search for the extension of your choice.

Since Firefox doesn&#;t have a built-in adblocker or VPN, the need for an extension becomes more critical. And its user-friendly extension store wouldn&#;t leave you disappointed. It also has a decent collection of third-party add-ons up its arsenal that is enough to checkmark the requirements for the end-user more often than not.

Since Opera is a Chromium browser, you could quickly try all Chrome extensions. Hence, it automatically translates to a more decadent collection than Firefox, which still has some catching up.

Browser Speed and Performance

Our Winner: Mozilla Firefox

While this isn&#;t a quantifiable term we could explain in plain numbers, speed is among the most critical factors in which a user generally rests their overall decision.

We decided to keep this determinant at the end because, by this point, you would have a decent idea regarding the plethora of features Opera beholds. And this ultimately leads to its downfall. Since most of its functionalities are directly baked into the browser, its associated processes make it a tad slower in everyday usage.

On the other hand, although not bereft of features, Firefox has endured high and extensive resource usage. And the fact that it lacks a native ad blocker and VPN seems to be a blessing in disguise for them, at least in this segment.

So the fact that Opera is based on the clunky Chromium with many built-in options tends to make it a bit slower than Firefox, which impressively manages the browser&#;s resource consumption.

Bottom Line

With this, we end this extensive and detailed comparison test between two of the most well-known players in the browser industry. While Opera outdoes its competitor with customizations and features, Mozilla comes on top in the Privacy and Speed segment.

Apart from that, both these browsers behold some nifty and useful features that make them standout players. Whereas Firefox allows you to determine how stringent privacy you prefer, Opera could call its My Flow, and Crypto-Currency features its USP.
