As I also see this on Mozilla/5.0 (Windows NT 6.0; rv:2.0b8pre) Gecko/20101118 Firefox/4.0b8pre ID:20101118112142 "Error Console" this might be related to bug 238559 too.

I guess either Mozilla, Yahoo! or even Adobe did something to fix this, but as of today I can play http://new.music.yahoo.com/ricardo-arjona/videos/view/vida--218722949 on Mozilla/5.0 (Windows NT 6.0; rv:6.0a1) Gecko/20110505 Firefox/6.0a1 ID:20110505030608 with Flash 10.2.159.1 There are still these errors in the Error Console: Error: window.external.msSiteModeCreateJumplist is not a function Source File: http://new.music.yahoo.com/ricardo-arjona/videos/view/vida--218722949 Line: 34 Error: uncaught exception: [Exception...

(In reply to comment #4) > Confirmed > I change status to RESOLVED WORKSFORME Do you also see the errors in Error Console? Should followup bugs be filled?
