Any suggestions? It is stuck trying to load a page, but I can't click on any links or buttons, nor can I quit or force quit. I have used force quit in the dock, in the menu, etc., and when I try to shutdown or restart, it says I have to quit Firefox first. I have also turned off my Airport connection, to no avail. Can anyone help me out? I am using a MacBook. Should I remove the battery to make it go dead? Thanks in advance! Gotta' love updates!
