Hey! Weird problem: I could not login via google, facebook or similar accounts on websites that support it. So I tried disabling all extensions and restarted FF without any luck. I then tried Safe Mode and it gets the job done but when I reset/refresh FF and get the extensions I wanted back it does not work again even if they are all disabled! any insight on that? is there like a hidden extension that blocks it? I'm on the latest FF for Mac (el cap)! thanks, your input would be highly appreciated!
