Kwok:
It was possible to get tab session restoration with several extensions pre-2.0.
They really need to make more extension features standard...

I had some crashing issues when I had a lot of addons installed that conflicted. Try dumping them all, upgrading to 2.0 and adding them back a few at a time.
Yeah, a new profile is usually a good step. You can copy the bookmarks.html file over to get all of your bookmarks resetup instantly. I would suggest you extract the bookmarks.html file from your profile folder, move the profile to a backup location, then delete all firefox files and install a clean FF 2. You can manually paste the bookmarks.html file into your new profile folder without issue (probably want to close FF 2 first).
