hello A.B.V., i understand that this issue is frustrating, but if you want to get constructive help in solving the issue please consider opening a new question turning it down a few notches and describing the symptoms of the issue & what steps you've already tried in a bit more detail and IMPORTANT: add the troubleshooting information once you're asked for it in the question process...

if you just want to complain, please use input.mozilla.org/feedback instead of the technical support forum.

thank you!

Days and days wasted following boilerplate instructions. Disabled hardware acceleration: Edit flash MMS.cfg file - pages freeze - pages turn white- ball spins endlessly. uninstalled - reinstalled the program ...uninstalled profiles...plugins on plugins off ...Win7 64bit - did system restore. What a total waste of time. Please Give us a chance to go back. Many report the same problem, yet you act like it's never happened and offer the same lame corrective steps.... Shame. Why lie??? Why lie??? Give us a link to revert, or tell us your done trying so we don't waste any more of our time our time in futility.
