Today, Mozilla unleashed Firefox 94.0 for desktop users across all relevant platforms, but also for Android devices. The list of new features and noticeable enhancements includes Colorways, site isolation enabled by default, as well as multiple performance and security improvements across all platforms.

Although it might not seem such a big deal at first sight, Firefox 94 is a rather important release for most users of this browser that has recently lost a huge share of the market over the last decade, mainly to Google Chrome. Available for all desktop users, Firefox 94 also hits Android devices today, while iOS users get Firefox 39.

Before moving on to the changes, I should also highlight that Firefox 94 marks the end of support for the Firefox 78 Extended Support Release branch. Now, the new such version of the browser is Firefox 91.3 ESR. Desktop users across all platforms should watch out for the following changes:

  • Colorways prompt on first run, which offers the chance to choose one of six new color themes.
  • Site isolation now enabled, to help defend against malicious sites trying to hijack sensitive information from other sites the user is visiting.
  • Automatically handled updates (in the background, so no more update prompts to disturb the user) on Windows.
  • The about:unloads page on all desktop platforms to manually unload the least-recently-used tabs.
  • Support for Apple's low power mode for fullscreen video on sites such as YouTube and Twitch.
  • Linux users get improved WebGL performance and reduced power consumption.
  • Firefox Multi-Account Containers extension with Mozilla VPN integration to use different server locations for different containers.

Android users get a new, customizable Firefox for Android Homepage that includes recent tabs, bookmarks, searches, and articles recommended by Pocket. This mobile flavor of the browser also gets a new feature, called Inactive Tabs (tabs not viewed for two weeks are automatically moved in a dedicated section of the tabs tray).

Now, feel free to go ahead and share your Firefox-related memories in the comments section. Are you still using it in 2021? On which platform(s) and why/why not?

In my early school days, I hated writing and having to make up stories. A decade later, I started to enjoy it. Since then, I published a few offline articles and then I moved to the online space, where I contributed to major websites that are still present online as of 2021 such as Softpedia, Brothersoft, Download3000, but I also wrote for multiple blogs that have disappeared over the years. I've been riding with the Notebookcheck crew since 2013 and I am not planning to leave it anytime soon. In love with good mechanical keyboards, vinyl and tape sound, but also smartphones, streaming services, and digital art.
