  • Firefox now supports correct color correction of tagged images using ICCv4 profiles.
  • The Shift + Esc keyboard shortcut now opens the Process Manager and provides a way to quickly identify resource-intensive processes.
  • Processes used in background tabs now use Efficiency Mode on Windows 11 to reduce resource usage.
  • The bookmarks toolbar’s default setting “Only display in new tabs” works correctly even with empty new tabs. As before, you can change the behavior of the bookmarks bar via the toolbar’s context menu.
  • Improved handling of non-ASCII characters when saving and printing PDF forms.
