Wht the ... !
Aila ! Mozilla Firefox has exploit too !!!… hurray…. ……… !! LOL
I was searching Security forums and found this it states that :
This exploit modifies the UID field in the cookies.txt file of Mozilla’s browsers in such a way that when the browser will try to access the phpBB forum it will be granted access with the user_id provided rather than the original one.
Donno How it works though
