Dang people are fast, first filed a dupe at the same time and then cannot dupe against.. since it got marked before I could do it..  :)

anyway.. flash sites take down the whole browser, have to kill Firefox.

Just backed out parts 3-7. Not everyone is seeing this bug but I don't want to find out the hard way how many people do see it.
