XP, 128 bit,ff3.6.17 now but no help. Since I updated both, in Facebook my system hangs repeatedly Only hard reboot and open new session will let me back on. I have been talking to Adobe support for 3 days and got the advice to put FF3.6.17 back on. It is worse when trying to scroll or trying to play a game. Cursor freezes and system hangs. I need some help pls. Which plugin is best when trying to use facebook and games on FF4.12? DOESN'T ANYONE KNOW OF ANY HELP? Just give me the name of a plugin that FF likes and a Web address. I need to be able to use my browser and would like to play some of my games. PLEASE!!!
