Before the update, there used to be a "Restore Session" button when I re-opened Firefox. It's gone now, is there any way to have it on the "New Tab" page again? I always quit the application to get the option to make a new window (because when I keep Firefox open for too long the option for making a new window from the dock disappears). I know that I can just go up to "History" and click "Restore Previous Session", but I would be grateful if someone told me how to get that button back. It was so useful!! P.S. I am using a MacBook Air.
