Flash videos without sound when using firefox. I have reinstalled plugins, flash player up to date. Sound is ok on IE 9. I cant listen to any Youtube videos using Firefox. I would like to keep Firefox as my main browser, but need to fix this problem. Can someone help me ?

or you can downgrade to version 11.2 of the flash plugin, until adobe provides a fix for those issues, see Adobe Flash plugin has crashed - Prevent it from happening again

what are your mozilla sound options? are all drivers up to date? are you doing something wrong?

Not sure if I correctly understood you "Mozilla Sound Option". Under Mixer, it is at the same sound level that every other application. Driver for SB Audigy and Unimodem half-duplex audio device are up to date. If I am doing something wrong, I don't know, hope not because I am just trying to play the video wit the same sound level it was a week ago. I also tried the Windows Fix It for possible errors, but it answers that no error was found and no correction is necessary. I just found the sound is not working on Google Chrome too (if that information helps), but it is still working on IE9.

Madperson, thank you for your post. I have downgraded to 11.2 (it was hard to find), but if finally solved the problem. Cant understand how Adobe distributes a new version without checking this kind of compatibility. I had to clean some registry's data to downgrade and had problems with the old version available in Adobe's site. Had to search a different source and it is working now. Thanks again !!!

I have done everything suggested on these posts; I have uninstalled everything, updated to the newest versions of Firefox and Adobe, I have uninstalled all my old Java platforms and installed the newest Java...and every time I compare YouTube playback, IE works flawlessly and Firefox is horrible, choppy, distorted. I can't do any more, so it's time to quit and return to IE. What a shame. Blame Adobe, blame Java corruption...Firefox has to step up to the plate here!
