I've noticed this sort of anomoly as well.

My system seems to "hitch" sporadically
 - I'll be typing in word processing software
and my system will freeze (sometimes for as long as 20-30 seconds)
every so often. I'll pull up Task Manager, and a firefox process will
be taking up a lot of CPU time.

I can't seem to be able to reproduce it,
so it only happens under certain circumstances.

I'll also add that I have yet to see it happen with the
latest version - though I've only had it for a few days now.

Is there any way to put some kind of a CPU monitor on my system?

I wish I could be more helpful - sorry.

Reporter, do you still see this problem with a Firefox 2 build and a new profile:

If not, can you please close this bug as WORKSFORME. Thanks!
