The many problems caused by the new Firefox 3.6.4 "hang detector" facility that led to Flash Player crashes has led Mozilla to release Firefox 3.6.6 with a higher timeout value.
Please update your Firefox if you have troubles with Flash Player on FF 3.6.4!
Thanks to eidnolb for providing the information about the Firefox update!
Thanks for the info.. its usefull....!
Firefox 3.6.6 with Flash 10.1 will play a flash video in full screen, but none of the controls work in full screen on some sites. I also had games like Farm town lock up when in full screen on facebook. I ended up going back to Firefox 3.5 everything works normal now.
I did do a fresh install of 3.6.6 and lastest flash before downloading Firefox 3.5,
