Added
Fixed
- Tabs: Suboptimal "tabs reload limit" logic and pending-mark styles
- History: Redundant and potentially harmful setting "Load history on demand"
Always load the history service on demand. Previously, if this setting
was disabled, the history service might never unload, handling all
visits and title change events and wasting CPU time. - History: Incorrect updating of titles
- Snapshots: Group/placeholder URLs are not migrated to a new profile
- Renamed container colors are not handled properly
- Add 'cyan' alias for 'turquoise' and 'gray' for 'toolbar'
- Keep old color names for snapshots and bookmarks (temporary)
- Tab preview:
- Removed the window-mode as it doesn't work correctly anyway.
- Changed "in-sidebar" mode from inline to popup-like preview.
Localization
Performance Improvements
- History: Improved handling of title change events
Optimizes performance when a large number of tabs frequently change their titles. Configurable via hiddenhistoryTitleUpdIntervalpref (ms, 0 - off, small values might cause performance issues). - Inactive panels are no longer rendered
Note: Due to https://bugzilla.mozilla.org/show_bug.cgi?id=1882408, the disappearing (leave) part of animation on panel switch will not work.
