Youtube doesn't work on firefox. The homepage won't open, and any links show a blank page. It works on Internet explorer, but I just want to know why.

how long have you had Firefox?

if you get it alittle bit ago i would redownload it

Do you have up to date Java? or any connection issues?
My firefox can run Youtube.

I downloaded it a few days ago.
And I have updated Java a few days ago as well.

Hmm, that is very strange. If Java is covered im not exactly sure

Update your Adobe Flash thingy if you have it, I had the same problem and it fixed it.
