Hey guys, I tried to download Mozilla Firefox, and it downloaded. I tried to open it, and now it just opens and closes in the dock. The icon appears, and disappears, and has been doing it for about 5 minutes now. I tried to click around, and I ended up opening another one. Now I've got two Mozilla icons opening and closing in the dock. I tried to force quit, and it doesnt work. I tried shutting down and restarting with the power button, but it says that Mozilla cancels the shut down process, so I can't shut it down. I guess I'm just going to have to wait till the battery dies, and hope for the best. Does anyone know what is wrong and how to fix it? Thanks P.S. Sorry, this might be something very obvious and stupid, but please forgive me, I'm still pretty new to OSX.
