OS X V10.7 Lion :: Dock And Toolbar Disappeared?Jun 16, 2012
The dock and toolbar at the top have disappeared from the screen. They re-appear when I click in the area where they should be but disappear once again whenever I click elsewhere. I have also lost the ability to minimize open windows. I can resize them manually, maximize and exit them I just cannot minimize them! (The orange button has gone grey.)
I have checked that I am not in fullscreen mode and I have unchecked all the automatic hide settings in the system preferences. This is only occuring when I'm using Mozilla Firefox.
I have a feeling that I accidentally clicked a button or unwittingly used a keyboard command to enter this setting, but I can't remember what I pressed!
