Opera GX vs Firefox – features, design, & security compared
UI & Design
Firefox and Opera GX are nothing alike, but are intuitive to use. Opera has made a conscious effort in improving user experience by offering some unique features with its GX browser.
Starting with Firefox, the design language is modern yet simple. Any type of user can get used to the functions and features offered by the browser.
Opera GX is a gaming-inspired browser. With a dark and red accent theme and Razer Chroma integration, GX can complement your gaming rig and match the theme.
You can pick from one of the pre-selected colors or any color you like by opening the Easy Setup function from the top right corner. Furthermore, you can customize the browser with custom wallpapers.
Due to better tab management and easier navigation to access advanced settings, Opera GX wins the battle between the two web browsers in Firefox vs Opera GX based on the user interface.
Firefox is known for its excellent memory management. It helps in faster data retrieval and response interval and is ideal for multi-tab users. It can handle heavy sessions without hogging and restrict RAM usage.
Opera GX is on par with Firefox when it comes to RAM management. However, the built-in resource management tool GX Control gives it an edge over Firefox.
GX Control consists of a few tools including CPU, RAM and Network Limiter. Once enabled, it allows you to set a limit on how much RAM, CPU and network usage your browser takes up.
When it comes to the Hot Tab Killer feature, note that it allows you to slash tabs that steal your resources.
While both the browsers offer excellent performance and use system resources efficiently, Opera GX offers more for advanced users to prioritize the resources depending on the task.
Firefox has an extensive add-on library. Although, it may not be as large as Chrome’s web store, you can find all the major extensions you want there.
The browser also comes with some handy built-in features, such as the screenshot tool. Right-click on any web page and choose the Take Screenshot option.
You can capture the full screen, choose a specific area or save a full web page. The images can be copied or downloaded to your computer.
Other handy features include a Reading mode that strips off unwanted contents from the web page and Pocket integration to save web pages.
Opera has its own add-on library, but, it is not as good as the Firefox add-on library. However, this Chromium browser fully supports Chrome Web Store extensions.
In our testing, all the Chrome extensions worked normally without any issues.
Similar to Firfox, Opera GX also offers some handy built-in tools, including a screenshot tool. You can take screenshots, add text, emojis and annotate and share it on social media.
Additionally, it also offers an intuitive Dark Mode feature. Right-click on any webpage and choose the Force Dark Mode option. Opera GX will show the webpage in darkmode.
Even more, being a gaming browser, GX comes with built-in streaming apps and social media integration.
The sidebar allows you to access popular streaming and social media apps, such as Twitch, Spotify, YouTube Music, Apple Music, Discord, and more directly from the browser.
Security and Privacy
Firefox offers excellent privacy features. You can choose what to block and allow from the settings. The company being non-profit means it is much easier to trust the company when it comes to user data.
Users can block trackers, cookies, crypto miners, and fingerprints from the settings. The Enhanced Tracking Protection blockers target over 2,000 trackers including trackers from companies like Facebook, Twitter, and more.
As for the Firefox Monitor feature, it can automatically notify you if your password has been breached.
Opera GX offers a similar set of privacy and security features as Firefox, in addition to free VPN and ad blocker.
The built-in ad blocker blocks suspicious and annoying ads on web pages. As for the VPN, you can access restricted content securely.
Both browsers warn you about suspicious pages by checking the active page against its database of phishing and malware websites.
Firefox and Opera GX offer great security features including a third-party cookie tracker blocker. Opera GX, however, has an edge with its adblocker and built-in which is not a standard feature across browsers including Firefox.
Which one is your choice?
Mozilla Firefox is an excellent browser when it comes to performance, design, security and features. However, for gamers and power users, Opera GX offers more.
Apart from the unique GX control feature that allows you to limit the CPU, memory, and network usage to your browser, it also comes with social media and streaming apps integration.
For those who want to make a switch from Firefox to a Chromium-based browser, Opera GX is an excellent alternative. It offers more features, better security, and greater control over your browser.
