I'm hoping that someone can explain what it is with Firefox and unresponsive scripts. I have two computers (different OS on both), but both have Firefox 30 on them. My newer computer also has IE and Chrome. Quite frequently, I get unresponsive script messages. The computer first starts running very slow and then the whole thing locks up until I can get the unresponsive script prompt cleared. I can't recall having encountered this issue with IE and Chrome, so I'm thinking it has to be something with Firefox.
