New Firefox Beta with Enhanced Performance

Mozilla

The latest Mozilla Firefox Beta is now available for testing on Windows, Mac, Linux and Android. This beta includes performance enhancements that improve the browsing experience for users and enable developers to create faster Web apps and websites.

New in Firefox Beta for Windows, Mac and Linux:
  • Optimized Memory Use: Reduces memory use and improves performance areas including responsiveness, startup and page load time, even in complex websites and Web apps
  • Improved memory management: The JavaScript garbage collector works more frequently to free up memory and improve performance when you have many tabs open or keep Firefox running for a long time
  • Enhanced Firefox Sync: Your data syncs faster when a bookmark or password is added or changed
  • Azure Direct2D for Canvas: Helps Firefox speed up HTML5 Canvas-based animation rendering
  • Web timing spec: Enables developers to measure page load time and site navigation so they can identify how to make website performance improvements
  • CSS 3 Text-Overflow: ellipsis: Additional way for developers to display CSS 3 text that overflows the layout area
  • Telemetry: Install this add-on and opt-in to report browser performance data and help improve future versions of Firefox
New in Firefox Beta for Android:
  • Optimized Memory Use: Reduces memory use and improves performance areas including responsiveness, startup and page load time, even in complex websites and Web apps
  • Enhanced Firefox Sync: Your data syncs faster when a bookmark or password is added or changed
  • Copy and paste: Copy and paste selected text from mobile websites
  • Restored session history and tabs: Firefox restores browsing history and tabs so users can easily return to their previous browsing session
  • Language selection: Firefox can detect the language setting on your Android device or allow you to select from more than 10 languages during initial set up

If you already have Firefox Beta installed, you will receive an automated update notification. You can also go to the “About Firefox” menu to apply the update manually.
