Firefox freezing/running slowly?
No one website or action seems to do this all the time, but I'll be running two tabs and no other applications and firefox will freeze or "beach ball" for over a minute. Sometimes it will unfreeze and then refreeze for another period of time as well. Very frustrating. Please help!

It's probably down to one or two plugins (add-ons/extensions).
Try starting firefox in safe mode and disable the plugins, etc.

Addendum:
I forgot to mention that I had a similar problem recently.
I started firefox in safe mode, but did not disable anything.
I then opened up the add-ons tab, unchecked the "update add-ons automatically" option (in the drop-list next to "search all add-ons"), and then I also clicked on "reset all add-ons to update manually".
That did the trick for me....
