Firefox won't click

[Konstantin Svist]

Hi,

I'm having a problem with Firefox: every once in a while 
(intermittently) it doesn't follow the URL I click and/or doesn't go 
back/forward in history. It just "blinks a little bit as if it started 
the process of changing pages, but immediately stops and stays on the 
same page.
If it's a normal URL, I click a few more times or reload the page and it 
starts working. Sometimes, though, it happens when I click on a button 
in web store(s) - the button becomes disabled (so as to not let me 
submit my order twice) but the request doesn't actually get to the store.

I have some extensions that might be making this happen... here are the 
ones that I think are relevant:
Adblock Plus
Fasterfox
Redirect Remover (set in "allow redirects" mode)
Tab Mix Plus


Does anyone else have this problem?

Thx
