browser stops working after recent update, requesting going back to previous version

Here is the main problem, today your update for firefox went live. Wich is great, however it caused mainly on websites like Youtube, the reaction that i can no longer enter without passing a CAPTCHA, giving excuses that i got abnormal internet traffic. I did not have this problem since before your update. So my request is to see if the update is can be reset back to its previous version. Because my idea is that this update is the main reason many websites are um-accesable.

I want to go back, too.  Update is terrible.  Every website I go to is slow and clunky now.  I won't be using firefox until this is either fixed, or I can go back to the previous version.
