Correct, that "clear cookies" problem only works ONCE, and if you disable the cookies for the youtube site, you can't log in any longer.

I understand this being thought a workaround before it was proven NOT to work, for anyone needing to sign in, but I don't understand why cor-el continues to post it as if it were an actual solution.

Ever since my Firefox updated to 13 I have been unable to view videos on you tube or videos on any website. I have to switch to internet explorer to have video.

Am getting real tired of having problems every time Firefox updates thinking of going to another browser as Firefox cant even be contacted to get a fix. I have to wait weeks sometimes months until someone else comes up with a fix. NOT IMPRESSED
