Firefox problems

[PZEROFGH]

ok, i just came back from vacation and i booted up my computer, opened firefox and now the bottom of the screen is taken up by this blank space, you know where it says loading on the very bottom, well that just extends about 1-2 inches above fromt he taskbar, and i cant see the whole firefox, i wish i can take a picture. how do you take a picture of your screen??? anyways i wonder how i can get rid of this.

dude don't use the full resolution for screenshots. lower it. i don't know but that looks strange, my first impression was that it had been dragged longer but i tried and it cant be done. try re-installing firefox

i tried dragging it down but i cant drag it, maybe a reinstallation will help.

EDIT: i ujst restarted my computer and its gone now for some odd reason, i didnt even reinstall. well thanks for the help
