Help with youtube

I know this might be a weird place to ask a question about youtube, but there's many experts on this kinda stuff so...

I can't watch videos on youtube while using firefox. With IE videos run fine.
While using firefox i can watch streaming videos of youtube on many websites. Is only when i'm on youtube that the message "an error has ocurred" appears.

I have the latest versions of mozilla firefox and adobe flash player. I have installed them both three times. Nothing works. Any ideas?

Thanks in advance.

Not sure I am using firefox version 3.6 and I don't have problems viewing youtube videos. I moved your post here to technical questions forum, mabye someone here can help.

I get the same Problem like many others some Mont ago.

Could it be that you installed the Add On >Downloadhelper > in your Firefox ?
The old Version of them make this Error with Youtube.If you have Downloadhelper -delete them - and install the new Version of Downloadhelper,the Bug is fixed..

Hope this is the Problem.

Thanks, I never thought that the problem could be the use of Downloadhelper
