 If Torbutton is enabled when Firefox boots, it makes two requests to
 check.torproject.org through Tor. If this request fails, Torbutton will
 simply try again, and again, and again, and again… Until a successful
 request is made, Firefox will not start.

 This causes two major problems. The more common and less severe one is
 that it dramatically increases Firefox's startup time. The second is that
 if the user is connected to a network that requires them to perform some
 action through a web interface (e.g. logging in or accepting a ToS
 agreement), they'll find themselves in a perverse, Freenode-esque catch-22
 where they can't connect to the network unless they disable Torbutton, and
 can't disable Torbutton until they connect to the network.
