Firefox opens, but I can only see it in my toolbar when I put my curser over it

trishcollier13

My Firefox opened this morning, full screen, but now it won't go full screen. The only way I can see it is by putting my curser over the icon in my toolbar. I've tried uninstalling and re-installing Firefox, but that didn't help either. When I've clicked on the icon, it seems to go over to the right side of my screen and get "lost".

Could you try the trick described in this thread and see whether it works for you: When I go to open firefox it shows up on my tool bar but not on my screen where is it?

The backup plan is to delete a settings file that stores the last-used window position. Since that also deletes all your toolbar customizations, let's set that aside as a last resort.

You can check for problems with the localstore.rdf file.
