Sidebar switcher allows users to access Bookmarks, History and Synced Tabs panels easily, quickly switch between them, move the sidebar to another side of the browser window, or close the sidebar.
It is now possible to copy any file from your operating system and paste it into Firefox.
You asked, and we listened! The volume slider is now available in Picture-in-Picture.
The keyboard shortcut to reopen closed tabs (command + shift + t) now reopens last closed tab or last closed window, in the order items were closed.
I like that I can now move my sidebar to the right, so much less sidebarception when working in sites that also have left sidebars.
