I installed FireFox 2 on my work PC, and it's working great. I'm not certain I like it any better than the old FireFox, but then I haven't really had a whole lot of time to explore it's features in depth yet.

However, I tried to install it at home last night, and something went bizarrely wrong... all of my bookmarks vanished, and tabbed browsing doesn't work... I can open new tabs, but have been unable to load any content in them... any sites I try to link to in a second, third, or even fourth tab just replaces the content of the first tab and the additional tabs remain blank.

I suppose I'd better roll back my system and try reinstalling it. Has anybody else experienced installation issues with the new FireFox, then?
