Webm doesn't play, breaks entire computer's sound output
I have a rather strange problem: I play a few .webm files, and everything works perfectly - until something happens (mostly after opening a new .webm video, doesn't have to do with the content itself, it just randomly happens whenever I open a new .webm) and the sound output on my entire system doesn't work anymore.
I then have to go to Control Panel -> Sound and have to manually de- and reactivate the sound output (speakers) to get it working again. I have no idea in what way Firefox, or .webm in particular, messes directly with the sound output.
System: Windows 7 64-bit FF version: 29.0

Can you try to start Firefox in Safe Mode to see if Firefox works properly with no error? You can start Firefox in Safe Mode below:
- Windows/Mac: Go to Help > Restart with add-ons disabled
- Linux: Run firefox -safe-mode in the Terminal/Konsole
If Firefox opens up fine with no problems, it's probably one of your extensions that's causing the issue. You can re-enable your add-ons one by one until you find the one that causes the issue upon being re-enabled.
