Firefox 95 is out, here are the changes

Yesterday, Mozilla made available a new Firefox version to stable version users. Firefox 95 is a minor release with mostly security and privacy improvements. Here are the key changes in this release.

Firefox 95

If you haven't disabled updates,  you should receive the updated version of the browser automatically. Otherwise, you can download Firefox 95 using one of the following options.


The latter link opens the file listing, organized into a few subfolders, including win32 for Firefox 32-bit for Windows, win64 - Firefox 64-bit for Windows. There are also mac and Linux builds.

What's new in Firefox 95

According to the official change log, the browser includes the following novelties.


RLBox is a new security feature that extends sandbox capabilities. It isolates subcomponents to make the browser more secure. RLBox has beeen created by Mozilla in collaboration with a research team from University of California San Diego and the University of Texas.

In Firefox 95, RLBox secures the Graphite, Hunspell, and Ogg modules on all supported platforms. But in the next version, Firefox 96, Mozilla will expand it to the Expat and Woff2 modules. RLBox uses WebAssembly to isolate potentially-buggy code. More details here.

Firefox on Microsoft Store

Firefox 95 is the first official update to the browser redistributed via the Microsoft Store. We recently wrote that the browser can be installed on Windows 11 and Windows 10 using the built-in Store app. Those who did that can now use Store as the default channel for browser updates.

Other changes

  • Reduced CPU usage on macOS in Firefox and WindowServer during event processing.
  • Reduced the power usage of software decoded video on macOS, especially in fullscreen. This includes streaming sites such as Netflix and Amazon Prime Video.

  • There is a fix for the web version of Slack that finally allows using calls and other media feature.
