I'm finding that Chrome hit sort of a decline from a personal peak in that current versions seem to be pigs on resource constrained systems, and has started to move backwards in terms of UI friendlyness (e.g. frequent requests for login to google accounts, rollout of more difficult user profile switching). IIRC the integrated flash plugin in Chrome is proprietary and at times it seems to be at the root of hanging processes or runaway resource consumption with Chrome. Ironically flash compatibility is one of the reasons I keep Chrome around - I've dropped flash plugins for all my other browsers...

I'm hoping it's a local max/temporary decline for Chrome, but Firefox now feels like the lighter of the two browsers in my use.
