We already have Ctrl+Q and Alt+F4 combinations for close window, Ctrl+Shift+W should work differently. It should close all tabs (Like Ctrl+W close current tab, Ctrl+Shift+W should close all), but not a window! This combination used to clear your workspace and start visiting new sites from scratch, but not for exit!

The tab bar should distinguish the active tab (in part) by removing its bottom border. When I restart Firefox, the tab bar displays correctly but before long that bottom border of the active tab reappears. Changing to a different theme doesn't help. All I can think of is that perhaps I have too many add-ons or bookmarks installed. (I currently have just under 50 add-ons.) What can I do to keep that bottom border off the active tab?

I have my Instagram tab pinned, as well as my Facebook Messenger tab, and every time I start Firefox, the Instagram tab is not pinned anymore. Yet, the Messenger tab is still pinned.

Is this a bug or a feature of the Facebook Container? I assume a bug since it only happens to my Instagram Tab.
