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.

Re: Certain youtube videos won't play in Firefox

Google this article : "How To Uninstall Firefox Completely And Remove All Traces Of The Application"...then follow instructions and after removing firefox, then reinstall firefox...all problems of youtube and other videos too are over, like a brand new computer...also when removing firefox you are asked if you want to remove personal data and settings too, mark it to do so...until you don't remove ALL TRACES of old firefox, you will have the same old problem , ....after uninstalling firefox by "add and remove" , and program files , is not a bad idea that on your "search" of the computer, type the word 'firefox" and delete whatever comes by firefox , also repeat same for the word "mozilla"...may be you need then to uninstall flash player and reinstall the latest version too

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/20-4QIWH2...[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.
