I have made a javascript which is working absolutely fine in IE and Opera. But in FireFox its dead. There's no error messages, nothing at all. Can anyone tell me whats wrong with it ?

My javascript is doing a ajax call and enabling / disabling buttons on result of that ajax call. Thats it.

I have tried to keep the javascript as simple as possible and it works great in IE and Opera but FireFox simply does'nt do anything.

Can anyone tell me if FireFox supports ajax etc. ?
