Firefox has been acting weird lately, showing an invalid certificate error for pretty much anything https. Some pages such as facebook and soundcloud load only sometimes and when they do, they're completely broken. Bitdefender found nothing but a few tracking cookies and MBAM found 3 PUP.Optional.Conduit.A, which were already removed. So, uh... What do I do?


EDIT: While both Firefox 23 and 26 act like this, IE, surprisingly enough, does not. I also noted that every certificate is issued by Bitdefender, which happens to be my AV. Could it have screwed something?


EDIT 2: Oh well, Google, once again, saved the day. Turns out Bitdefender's SSL antiphishing analysis tool happens to screw with Firefox's security certificate validation.
