I am having a volume problem in my Mozilla Firefox browser. I can't really explain it...but on my actual computer, like in games and random sounds (like in entering/taking out things, error sounds) and programs like iTunes and Windows Media Player, I have sound. But in Mozilla Firefox, I can't hear ANY videos! This includes sites like Youtube, video.google.com, dailymotion.com; basically all of the major video sites.

Any and all help is appreciated! *By the way, I'm running Windows Vista, on an Acer notebook.

it should be working if i was you i would check with acer and see if there was a new driver for the sound chip in your laptop and also check there forum and see if any else had the same problem
wish i could be of more help
good luck and take care
