The F11 key can be used to toggle full screen mode.

Please don't dig up 8 month old threads to provide an answer that isn't even related to the "owner's" question. The Maximize / Minimize control button has nothing to do with Full Screen mode being toggled on.

If you Google "firefox full screen" (or something similar), this is the top hit. That's how an 8-month old thread gets dug up. No point in getting upset when that happens.

... and apunter is correct. The original question was, "I made my firefox full-screen; how do I change it back?" Pointing the mouse cursor toward the top right corner of the screen brings up the minimize/restore/close buttons and clicking the restore button does indeed get you out of full screen mode. It will not put you *in* full screen, but it can get you out.

Remembering F11 toggles full screen mode is probably easier, though.
