Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.6) Gecko/2009011913 Firefox/3.0.6

When I visit www.youtube.com to view any videos I get an error that reads "We are sorry the video you have requested is unavailable." I have tried several videos and each one had the following message. I then tried the videos with the IE tab extension inside of FireFox and the videos played normally, and with no problems. When I switched back to regular FireFox the videos instantly became unavailable again.

Reproducible: Always

Steps to Reproduce:
1. Visit www.youtube.com
2. Click on any video that you wish to view
3. When taken to the page the video will be unavailable under normal FireFox, but under IE they are available.
Actual Results:  
No videos are playable with FireFox, but with IE they are played.

Expected Results:  
FireFox was working fine with the previous version I updated to 3.0.6 and now I cannot get playback of any videos

This works fine for me (Windows XP, Vista, 7). Do you have the latest flash plugin?
You may want to try the basic trouble shooting like safe-mode, a new profile and a reinstallation in a empty folder:

No reply in more than half a year, closing this bug as INCOMPLETE. 
Please reopen with more information if you still can reproduce the issue with the latest trunk nightly build and a new profile:
