Opera vs Firefox: Features and performance comparison

Opera is the browser that has always been there on the desktop and since the beginning of mobile, it has been the browser that has been unchanged and always been on the top.

Opera , the most popular alternative to the popular internet browser Firefox, has been updated to version 20 with new features and performance improvements. It was announced on November 8, 2018, and the major update was released on the same day. Although the main update focuses on both new features and performance improvements, there are minor improvements to the UI and support for HTML-5 video also.

Opera has always been a popular browser on the desktop, but Firefox is now vying for that crown. That’s great news for Firefox fans, but it means that Opera is going to have to up its game if it wants to dethrone the King. But is it really that easy? We decided to put their features side by side to see where the browser makers stand.

The main difference between Opera and Chrome is the sidebar, which allows you to quickly access certain features or move from one work area to another. Some users don’t like this feature. If you want to save space, you can disable the sidebar in the settings. As for customization, the browser has a simple control panel that lets you switch to a light or dark theme. You can customize your browser with some of the available wallpapers, but you can also download additional wallpapers or add your own. You can adjust the start page via a simple control panel. You can change the size of headlines, display speed dial offers, or enable a news feed on the home page. Firefox: Extensive interface customization Firefox also has a clean interface, but we must admit that Opera’s interface is more elegant in our opinion. The home page contains a search bar, a list of most visited sites and navigation highlights. The Highlights section contains visited pages, bookmarks, recently downloaded and saved pages, so you can access them with one click. The top sites section is customizable, and you can easily add a site, collapse the entire section, or hide it completely if you wish. As for the base, you can choose what type of content to display there, and you can hide the entire area if you don’t want to use it. You can even manage the number of lines in the Best Pages and Highlights sections, which is nice. As for customization, it should be acknowledged that Firefox offers a wide range of customization options, and you can tailor the toolbar to your taste. You can remove toolbar items, rearrange them, or add just the icons you need. You can also minimize the icons and choose one of the four available themes.

Browser functions

Opera: Instant messaging, social media integration and more In terms of functionality, Opera works like any other web browser, but it has some unique features that may be of interest to some users. One of Opera’s most useful features is workspaces. With this feature, you can easily organize all open tabs, which is great for multitasking. Do you want to separate the professional and private tabs? Just move them to this workspace and that’s it. As for switching workspaces, you can switch to the desired workspace with a single click on the sidebar. If desired, you can assign keyboard shortcuts and use them to switch immediately to the desired workspace. You can have multiple workspaces, and each workspace can have a unique name and icon, so you can easily distinguish the workspaces. Another great feature to help you manage your tabs is the Tab Search feature. With itit, you can easily search for any open tab and find it in moments. Use the search icon or hotkey combination to open the search window, type in the name of the tab, and it immediately appears in the list. The search can also detect the content of pages, so you can search for a line and find all open tabs whose content contains that particular line. Both features are incredibly useful, especially if you’re multitasking and have dozens of tabs open, and we wish more browsers would include them. Opera also makes it easy to share files and links on your mobile device with the Flow feature. Install Opera on your phone, connect it to your PC and you’re done. You can share links, text and files from your browser by simply clicking on the Flow icon in the toolbar. This feature is reminiscent of Messenger and gives the impression that you are sending messages to yourself. In general, it is a quick and easy way to send data and links from your computer to your mobile device and vice versa. If you want to stay in touch with your friends, we can inform you that Opera supports several instant messaging services, including Facebook Messenger, WhatsApp, Telegram and VK. You can open them in the sidebar and chat with your friends while browsing the web. If you’re more into social media, you might find the built-in support for Instagram and Twitter more interesting. With this feature, you can always follow your feed and make sure you don’t miss anything. For all the music lovers among you, we’re happy to announce that Opera has a built-in music player and you can play music from various streaming services. Supported services include Spotify, Apple Music and YouTube Music. You can minimize the player at any time and easily control the music playback from the sidebar. Opera also has its own newsreader, but it’s not enabled by default, so you have to enable it manually. Once activated, you can choose from a list of sources or add your own RSS feeds and follow the latest news from your favorite sources. The last feature to mention is the screenshot tool, which allows you to take screenshots of the websites you visit. Once the screenshot is created, you can add pointers and text, blur certain areas or add highlights, which is very convenient because you don’t need to use any third-party tools. Opera has a lot of features, and while some of them, like workspaces and tabbed search, are extremely useful, others can seem gimmicky to some. We usually only use the basic features to improve performance, but for casual users the addition of a music player, messaging and social media integration can be useful. And even if you don’t plan to use these features, you can disable them so you never use or see them again. Firefox: Only the bare necessities In terms of features, Firefox offers less functionality than Opera, so you won’t find flashy features like music players or social media integration. Instead, Mozilla has taken a minimalist approach to improving the web browsing experience. You will find all the standard browser features in Firefox, so we will focus on the most unique features. First, there’s a sync feature that stores your browsing data in the cloud, so you can keep browsing on any device. You can also use this feature to send tabs to your phone, and while this feature is useful, it doesn’t work as well as the Flow feature in Opera. With this function you cannot send files or texts, only links. The sharing interface is also pretty simple in that it relies on context menus, so you can’t see the history of shared links. Firefox has Pocket integration that allows you to save any page and read it later on any device. Just click on the Pocket icon in the address bar, register a Pocket account and you’re done. Pocket as a service is pretty good, especially if you read a lot. So it’s ideal if you want to build a collection of articles to read. Firefox Lockwise is another interesting feature that works like a password manager for Firefox. This feature allows you to see all the passwords stored in Firefox. There’s even a special mobile phone application that lets you have all your Firefox passwords on your phone. This feature supports import, so you can easily import all saved passwords from other browsers. Of course you can create your login details manually, but in most cases Lockwise will ask you to register your login details when you log in to a website.

Run a system check for errors

Press Start Scan to check for Windows problems. Press Repair Everything to troubleshoot proprietary technology. Run a PC scan with Restoro Repair Tool to find errors that cause security problems and slowdowns. Once the scan is complete, the recovery process replaces the damaged files with new Windows files and components. This feature also generates a unique and secure password for each website you register with, ensuring your password is safe and unique. While this feature is incredibly useful, there are some problems. For example, if you click on a suggested password, it will be automatically stored in Lockwise, but your username or email address will not be stored. This can be frustrating because you have to manually update the data. To avoid this, you can use the arrow keys to choose a suggested password. Then enter your username, and the password and username should be saved. This is a minor bug, but it may affect your browsing experience. We hope this will be improved in future versions. Once you have registered your password, you will be asked to enter your password when you try to log in to this website. For an extra level of security, it is possible to set a master password, so that others cannot see or use your passwords without a master password. Another feature worth mentioning is Firefox’s screenshot utility. Allows you to easily take a screenshot of a specific section or an entire web page. The program automatically selects parts of the web page to speed up the process, but you can also manually select the area you want to capture in the screenshot. Unfortunately, there is no way to edit screenshots. This means that you cannot crop or blur parts of the screenshot. Compared to Opera’s screenshot tool, this screenshot feature is quite simple, but it works well if you don’t need to edit anything. Another useful feature is the reading mode, which allows you to avoid unnecessary page flipping and focus only on what is important. Once you are in reading mode, you can set the font, font size, paragraph width, line spacing, and color theme. There is also a text-to-speech feature, which allows the computer to read articles to you. Of course, you can adjust your reading speed and skip certain paragraphs if you wish.

How secure is Opera compared to Chrome and Firefox?

In terms of security, all three browsers offer similar features and use a sandbox to separate tabs in processes so that if you visit a malicious site, it stays within that tab. These browsers have similar privacy features, but there are some differences between them that you should be aware of. Opera: Powered by Chromium, integrated VPN and ad blocker Opera has a built-in ad blocker and anti-tracking feature. Although it is not enabled by default, you can activate it with one click. With this feature you can improve the loading time of your pages and, with anti-tracking protection, you can prevent websites from tracking your browsing habits. Unfortunately, Opera doesn’t use Google Safe Browsing, instead relying on other services. This is not a serious problem if you do not visit dirty sites and if you use a reliable antivirus program. The browser has a built-in VPN that offers unlimited bandwidth. While this feature gives you an extra layer of privacy from your ISP, you should know that free VPNs have their share of problems. Free VPNs are known to record user activity, which can be a problem for some users. In addition, some privacy advocates have issues with Opera’s privacy policies and data collection. Since the browser is not fully open, there is no way to determine how Opera uses this data. Overall, Opera offers solid protection and is perfectly safe for everyday tasks. However, if you are very concerned about your online privacy, Opera may cause you problems. Chrome: Google Browser Juggernaut Google Chrome is known as a safe and regularly updated web browser. So you don’t have to worry about your security when you use Google Chrome. Google did introduce a Do Not Track feature and its own ad blocker, but these features are hidden in the settings and less informed users are unlikely to find them. Google also has a history of collecting and tracking data for the purpose of displaying personalized ads. This is one reason why many privacy advocates are concerned about Google Chrome. While the browser is completely secure and among the safest on the market, Google’s privacy policies and data collection may be an issue for some. Firefox: Confidentiality and open source orientation Firefox is owned by a non-profit company, and because the software is open source, users can examine the code and ensure that their data is not sold to third parties. The software has advanced anti-tracking protection that blocks tracking cookies and certain ads. Firefox also has protection against phishing and malware and can block cryptocurrencies. Firefox even has a simple password manager that generates a strong, unique password for each website you log into. Overall, Firefox offers a lot in terms of security and privacy, and because it is open source, it is one of the best options for privacy and security-conscious users.

RAM usage in Opera vs. Firefox

Finally, we need to talk about performance, and for this segment we decided to measure the performance of Firefox and Opera on a low-end computer. Opera: Optimized for performance In terms of performance, we were quite surprised by the low amount of memory Opera used. At rest on the home page, the browser used no CPU and only 129 MB of RAM. We tried watching videos in Full HD on YouTube with five tabs open in Opera. The processor load was up to 80% at times and the memory was about 510 MB. This is pretty normal when loading pages, and we didn’t notice any major delays when using the browser. If you want to improve performance, we recommend activating an ad blocker to block ads and make your pages load even faster. Opera also offers Tab Snoozing, which puts inactive tabs to sleep to save your memory. This feature is especially welcome on low-end PCs. Firefox: A simple alternative At rest on the home page, the browser consumed 0% CPU and about 248 MB RAM, which is slightly more than Opera. We repeated the same test with five tabs open and a YouTube HD video download running in the background. During this test, Firefox used almost 700 MB of RAM and up to 60% of the CPU. However, Firefox’s CPU usage is lower, but its memory usage is slightly higher. As for the rest of the performance, we didn’t notice any major slowdowns with Firefox. As you can see, Opera consistently uses less RAM, while its processor is slightly larger than Firefox’s. Overall, we were satisfied with the performance of Opera and Firefox on our low-end machine.

Opera vs. Firefox : Supplement

Opera: Wide range of functions and low memory requirements Opera offers some unique and interesting features, including the Workspaces feature and the Tabbed Search feature, which will be very useful for anyone working with multiple tabs. There’s so much more to it! For Chrome Advanced tab management features Low RAM usage Built-in ad blocker and anti-tracking protection Integrated VPN Cons Some functions may be redundant Opera Flow is also a nice addition, being one of the easiest and most convenient ways to share files and links from one device to another. Ad blockers and anti-tracking are welcome features that improve your performance and protect your online privacy. By the way, the built-in VPN is also very handy and gives you an extra layer of security and privacy when browsing the web. Features like instant messaging and social media integration may be useful if you are an active social media user, but we found them to be redundant. The media player can be very useful, especially if you tend to listen to music online while browsing the web. Overall, Opera offers unique features, and its low memory usage makes it one of the best browsers for low-end PCs. The only drawback might be a small privacy issue, but that won’t bother you too much.


With so many unique features, Opera seems like the perfect browser choice for you! Firefox: Open source and lightweight Firefox’s greatest strength is its security and the importance it places on user privacy. It is free software, so you can be sure that your personal information will not be collected. For Open source Developed by a non-profit company Advanced anti-tracking protection Contains only the most important functions Integrated password manager Cons No built-in ad blocker Anti-tracking protection prevents websites from tracking you and ensures that websites cannot collect data about your browsing activities. Firefox also has a handy password manager that lets you protect all your online accounts with one secure password. The browser doesn’t offer any flashy features, and you’ll only find the most essential functions in Firefox. Memory usage is slightly higher than Opera, but not too alarming. Thanks to its low memory usage, Firefox should be the ideal choice for low-end PCs. If you’re looking for a privacy-oriented browser with only the most essential features, Firefox is for you. ⇒ Download Mozilla Firefox Overall, Firefox and Opera are both excellent in their own way, and if you’re looking for something with new and interesting features, Opera is the better choice.
