I accidentally dropped firefox from full-screen to half-screen and set it to fullscreen again, but when i open firefox, it... well, it does not look very ok...
well, when i click on the upper bar, it looks like that:
here it seems that firefox is drawn too far left, when i enter an url, it does not show until it is long enough... after another click in the bar, it is really full-screen...
how can i get rid of this problem?
Removing Firefox, deleting the ~/.mozilla directory and reinstalling firefox did the trick, now it works again :)
Maybe try closing the process or restarting ubuntu, if you haven't yet. Your problem might be only temporary.
