Youtube video no longer plays on Firefox after flash upgrade

Since upgrading flash plugin for firefox on ubuntu 11.10, youtube videos are blank with no way to start them. I have researched the problem on the internet for the last few weeks and it seems hundreds of users have the same problem but no one has any fixes. I can't believe this has not been addressed yet.
