WOT, BetterPrivacy, Adobe Flash, FoxIt, Silverlight, Flashblocker, FlagFox. Those are the only ones I used. Basic stuff. If FF can't handle that, than I can't use FF...
Chrome still has issues rendering some web pages, including TomsHardware. But that is why I still keep what had been the unstable FF 3.5-3.6 FF around at all. This last update has been a HUGE improvement for FF making it feel a lot more like FF 3.4 in terms of speed and stability. But that was 6 months of people FF will never get back.
