Firefox No Audio On YouTube Since Update

I found the problem also on the Adobe forum after many computer changes.The video loads as muted and you have to click the volume icon in the lower left to hear audio.
Unbelievable. :) Version 25 coming soon.
I spent 2 hours needlessly googling and updating to watch a 5 minute video. :M

Is there some place that this problem could be reported?? Looked at mozilla.org but couldn't find a place to report problems.

That's interesting. Seems I have the same problem. But rebooting didn't help. The sound system on my desktop is alive but no sounds. But I guess I'll re-check a few things.

My audio messed up too after installing FF v24. My router also quit working on the wireless side only. Never happened before on any FF updates. A re-boot corrected everything.

Yep...whenever I bring up a youtube video... the sound bar slider is all the way down..

very strange

I had that problem too. At the bottom of the video is, also, a thing to adjust for sound.....turn that to max. Then make sure your computer is also turned up. I don't know if that's your problem, but it was mine!!
