Hello, Firefox is my #1 go-to browser and I basically use nothing else. I do have a suggestion that I really wish you guys will add to the "Context Menue". I'm on the mac 8 hours a day and the less I have to move my hand and arm around the less fatiguing and less strain on my wrist reducing Carpal Tunnel.
The #1 command I wish for is adding a command in the "Context Menue" (Right Clik) that allows me to close a live active window in the browser "Close Window" or "Close Current Window", Simple!
Best, Joe
