Firefox 117

Firefox 117 is a new development branch that has the following new features according to the release notes.

• mmacOS users can now control tabbing of controls and links via about:preferences.

To avoid unwanted results on websites that set their own behavior when pressing shift+right-click, Firefox now has a dom.event.contextmenu.shift_suppresses_event setting to prevent the context menu from appearing.

But there is also a bug fix:

YouTube video lists now scroll correctly when navigating with a screen reader.

As well as the following change:

Firefox no longer displays its own screen share indicator on Wayland desktop environments. Instead, it uses the system's default sharing indicator.
