My pages won't load when i click them

ok. just days ago, everything was just perfectly fine. idk what happened, but roughly 2 days ago, my internet started going goofy. not majorly but it's really annoying and i can't do much anymore. really, its all on facebook. i try to click on groups or links for whatever they may be for and my page will just sit there. nothing would happen. i can click a million times and nothing will load. can anyone tell me what i can do to make it so everything will load when i click on them? im using firefox in case that could have somthing to do with the problem. i didn't have this problem with IE.
