Howto-Upgrade: Firefox 48 Released, Multi-Process Enabled

Last updated: August 3, 2016

Firefox 48

Mozilla Firefox 48.0 was released on Tuesday. The biggest change is that Electrolysis (E10S), the multiple processes architecture, is beginning to be enabled by default.

Electrolysis is the project name for Mozilla’s efforts to split Firefox into multiple processes to improve responsiveness, stability, and security. The first phase of this work was to split Firefox into a UI process and a content process.

Besides enabling E10S for some users. Firefox 48 also features:

  • Download Protection: potentially unwanted software and uncommon downloads.
  • Add-ons that have not been verified and signed by Mozilla will not load
  • Better Canvas performance with speedy Skia support for Linux
  • WebRTC embetterments:
    • Delay-agnostic AEC enabled
    • Full duplex for GNU/Linux enabled
    • ICE Restart & Update is supported
    • Cloning of MediaStream and MediaStreamTrack is now supported
  • Searching and various security improvements, and more at release page.
