Motorola Q9m / Q9c

i use facebook a good amount, and when i first got the phone i was able to go the a certain facebook login page (not the first one but a different one) type in my user name and password, and log in...now when i press login it does a little dance, then stops loading and the login button is deactivated. Does anyknow know of another browser to load onto this phone or what the proble might be? it's so wierd that it just stopped working. thanks in adavance
