What's new in this version:

New:
- You can now show tabs from other devices in the Tab overview menu.
- Firefox now supports touchpad hold gestures on Linux. This means that kinetic (momentum) scrolling can now be interrupted by placing two fingers on the touchpad.
- GPU-accelerated Canvas2D is enabled by default on Windows.
- Desktop mode browsing is now enabled by default for large devices on Firefox for Android. This can be controlled via a preference under Settings in "Site settings" previously named "Site permissions".
- When copying text to the clipboard in Private Browsing mode, Firefox for Android now handles it as sensitive content. The toast notification for the clipboard is masked on Android 13 and higher.
- Firefox now has a new anti-tracking feature enabled in Enhanced Tracking Protection "strict" mode: Bounce Tracking Protection. This protection detects bounce trackers based on redirect behavior and periodically purges their cookies and site data to prevent tracking.

Fixed:
- If we have the server time, we adjust the "expire" attribute value by adding the delta between the server and the local times. If the current time is set in the future, we consider valid cookies that are not expired for the server.
- Fixed an issue that started with macOS Sonoma where the emoji picker would open and immediately close when opened with the Cmd+Ctrl+Space shortcut.
- Thanks to research by Carlos Duarte do Nascimento (Chester) and :bintoro, and a patch by Carlos Duarte do Nascimento (Chester), we have been able to fix this universally for this shortcut and similar shortcuts going forward.
- Fixed an issue that started with macOS Sonoma where the emoji picker would also insert the character "e" in the selected text field/box when opening the emoji picker using the Fn+e shortcut.
- We have also fixed this for similar shortcuts using the Fn key.
- The "Picture-in-Picture: auto-open on tab switch" feature from Firefox Labs now behaves more reliably on more sites - auto-opening more videos that you care about, and ignoring ones that you probably don't care about.
