I've had a weird problem with the sound on videos going out sporadically and becoming staticly when playing vine and youtube videos. often youtube videos will display static and an error message. Also when the sound goes out it wont even play in the sound test in windows. This problem occurred after I updated to version 34. I reinstalled my sound drivers but that didn't work. I reinstalled flash player and that didn't work. I uninstalled all other plugins and that didn't work. I finally reinstalled the prior version of firefox ver 33 and that seems to have fixed it. I know degrading versions is a security risk so I hope that this issue will be resolved in the next update.

nah. Those steps didn't help me fix the issue. downgrading Firefox to 33.1.1 did however.
