just an idea:
If you enabled "Restore previous session" and had a lot of stuff open when
you left off the last time, perhaps you want to repeat this test with a
"clean" session - probably the easiest would be using a different user
account, though I'm sure firefox-savvy people will be able to show you ways
of doing this with your own user account w/o having to dump your usual
settings.
This may show you whether it's an issue with firefox per se or the pages
you loaded.
