  • The sidebar to view tabs from other devices can now be opened via the Tab overview menu.
  • GPU-accelerated Canvas2D is now enabled by default on Windows providing a performance improvement.

Update: To get the update now, select "Help" from the Firefox menu, then pick "About Firefox."  Mac users need to select "About Firefox" from the Firefox menu. If you do not use the English language version, Fully Localized Versions are available for download.
