I've had this problem since yesterday, youtube videos will not load, not even the ads(example pic below). all i'm getting is a blank player with the buffering symbol. I've tried other browsers to no avail, tried clearing cache, firefox safemode, re-installing adobe flash, reinstalling Java, reinstalling firefox, restarting the router, i even tried a system restore. Virus scans came up clean, theres no issue with my firewall blocking it, other computers on my network will play just fine, just not my pc. Running the latest version of firefox, flash, java, etc. Any help is much appreciated.
