youtube won't play in ff 3.6.18, have Adobe Flash latest version, however othersites' video does play

Flash version WIN 10,3,181,34

Opperating system Vista Home Premium service pack 2

This problem only appears with youtube videos. Other websites' videos run.

Tried reinstalling Flash and unchecking the hardware acceleration feature in Flash player settings, no effect.

AdBlock Plus (ABP) has caused that problem on Youtube in the past. I do not experience the problem with youtube with ABP active. You can test by:

  1. opening youtube in a tab
  2. click the ABP icon and choose "Disable on this page only"
  3. try to play some videos and see if youtube now works for you
  4. If that does not work, before you leave the youtube page, once again click the ABP icon and click "Disable on this page only" to remove the check mark, then close the youtube page/tab.

Tried your suggestion, no effect.

Video doesn't play, same message displayed: "An error occurred. Please try again later." However, it plays in Google Chrome.

Thanks for posting and letting other users know of the solution that you found.

Would you post the step-by-step that you used so that other users can follow. I assume it was by changing the Page Info Permissions.

Sure.

Right-click on any www.youtube.com page - not on a video - and select ' View Page Info'. Under 'Set Cookies' select 'Block.'

or:

If using a cookie managing add-on, such as CS Lite https://addons.mozilla.org/en-US/firefox/addon/cs-lite/ follow the procedures of the add-on to block cookies while on any www.youtube.com webpage.
