Mozilla has released the new browser versions Firefox 94.0 and Firefox ESR 91.3.0. The developers have eliminated several security vulnerabilities and there are new color schemes to choose from. The new Firefox version 94 is available for Windows, macOS and Linux.

The update to Firefox 94.0 eliminates at least twelve security vulnerabilities. At least seven are identified as high risk. Some might be useful for injecting and executing code.

For better protection against malware attacks, Mozilla introduces the Site Isolation technology. The content and code of each loaded website end up in a separate process. This should protect against so-called side-channel attacks, such as those against Intel CPUs such as Specter.

Color Moods

In addition to the usual themes (light, dark, Alpenglow, System) Firefox 94 comes with a number of new colors that you can choose between depending on your mood. There are 18 variants available, but they will only remain until the New Year - with Firefox 96 they should disappear again, except for the one you selected.

Performance Tuning

In order to achieve more speed with less memory requirements, the developers have made a number of minor improvements. In this way, memory that is no longer required is released more quickly and the CPU load has been reduced for some processes. In the case of mobile devices, this also benefits the battery life.

In addition, the so-called Tab Unloading functionality has already been integrated with the last version. This can noticeably reduce RAM usage by unloading inactive tabs to free up system resources. Version 94 now also brings the about:unloads page, on which all important data and information on the individual tabs can be viewed.

You can read more about the new version 94 in the Release Notes.

If you have already installed Firefox, it is best to use the update function integrated in Firefox. This will automatically provide you with the update Firefox 94.0 as soon as it is available for your Firefox.
