The Vivaldi browser has a great feature called Quick Commands which makes switching tabs, opening bookmarks, or just searching through tabs really easy. You can do it all from just your keyboard. Since I typically use Firefox, I decided to build a similar feature into Firefox. Introducing FF Quick Commands!

FF Quick Commands brings a Vivaldi-inspired command window to Firefox. Hit Shift+Cmd+K on Mac (or Shift+Ctrl+K on Windows/Linux) from almost any page, and you get instant access to your open tabs, recently closed tabs, bookmarks, browsing history, and built-in browser commands, all in one searchable view.
You can navigate results with the arrow keys, hit Enter to go, or Escape to close it. You can also customize which sources show up in the palette via the extension preferences.
