Certain youtube videos won't play in Firefox

Firefox 20.0.1, windows 7, flashplayer up to date.

Certain youtube videos won't play. The advert beforehand plays, and then the video just displays a black screen, no loading, trying to skip to a later time in the video doesn't work. It seems to be certain youtube users whose videos won't play, users whose videos I was able to watch only yesterday. The featured video on the user's channel is watchable, but not when opened separately. IE won't show the affected videos either.

Hi!

I'm sorry that you are having issues with Youtube. It seems this is a problem in the Youtube side as it has been reported as a known issue in their forum:

http://productforums.google.com/forum/#!category-topic/youtube/playing-and-watching-videos/20-4QIWH2yY[1-25-false]

Take a look to that link, a Youtube representative is updating the status regularly.

Best, Ibai

In addition to these symptoms, I've noticed that I can view these troubled videos on my cellphone just fine, but neither my XP or Win7 machine, which have all software updated can view. So if it was on youtubes side, it wouldn't work on my phone either.

Problem solved! I downloaded and installed Firefox 24.0 Beta. Apparently Mozilla programming team made all the right changes in the new release. Now all videos starting working on Youtube, Yahoo and BBC.
