Firefox will not play sound on any online videos...I've gone to your help page and tried everything, but nothing seems to fix this. I even upgraded to Firefox 5.0 and made sure all of my plug-ins are up to date but still no sound.

See:

You can click the Volume icon on the Windows Taskbar near the clock and click the Mixer link at the bottom to open the mixer.
You can adjust the volume level for each application in that window, so make sure that Firefox is not muted or set at a low level.
You will only see the Firefox program in the Mixer if you are on a website that plays sound.
Also check the volume setting for the plugin-container process.

I tried those already...still no sound...sound was working fine a couple of days ago...scanned for viruses, in case that was the culprit, but my computer is clean so not sure why sound doesn't work on Internet.

I have had this problem for a few days, no sound in Firefox, but IE and WMP (offline) have sound, this is a Firefox ONLY problem, so the volumes are all set correctly and the drivers and needed files are there, I've tried every fix that people have suggested on Google like checking the flash player settings, creating the "missing.reg" registry file and importing it, etc...

nothing works, I may just have to switch to Safari or Chrome, I watch a lot of video online (Youtube, ESPN3, NFL.com, etc.) so this is a huge problem...
