Firefox 105.0 New Features and Improvements

Firefox 105 is a smaller version which is a bit light on new features. One of the major changes in Firefox 105 is that Mozilla was able to significantly reduce the number of browser crashes due to Windows running out of memory in the release.

A fairly simple sounding tweak ensures that the main process of the browser is not compromised when the system runs out of memory. Instead, content operations are first on the chopping block to free up memory. Killing the main process kills the entire browser, while terminating content processes only disables the web page that is open in it.

Similarly, Mozilla notes that it has improved the out-of-memory behavior of Firefox on Linux as well:

Firefox on Linux is less likely to run out of memory and runs more efficiently for the rest of the system when memory is running low.

Other changes and fixes

  • The print preview dialog has an option to print only the current page directly from it.
  • On Windows touch devices, Firefox now supports swiping to move between touch gestures (two fingers on the touchpad have been swiped left or right to make history backward or forward).
  • Improved touchpad scrolling on macOS.


  • Searching in large arrays is twice as fast in Firefox 105 thanks to replacing the array, including and array.indexOf with an improved SIMD version.
  • Firefox is compliant with the User Timing L3 specification.
  • Firefox supports split service workers in third-party contexts.
  • Added support for defining firmware scripts using scripting.
  • The TextDecoderStream and TextEncoderStream interfaces are now supported, and are part of the Encoding API,
  • Offscreen Canvas DOM API support with full context and font support
