Can't log in after update to 33

Hey guys,

a lot of our customers can't log in on our site using Firefox after updating to the newest version (33). It always works in a new private window, and clearing the cookies seems to solve this problem, but most of our users have no clue what cookies are, so asking them to fix this themselves is generally not the best idea.

We wish we wouldn't be forced to tell those users to change Firefox to any other browser, as it's often easier than clearing cookies. So, are there any guidlines of using cookies on a website so it doesn't crash after updating Firefox? Cause maybe we could improve something on our site? Or our only hope is to wait till you guys fix your update process someday?

Thanks in advance!

If clearing the cookies works then maybe look at the code that validates the cookies that Firefox sends to make sure that you ignore and delete the cookie(s) in such a case and make the browser store a new cookie, so it will work on the next login.

A new PB mode window doesn't use the cookies from the regular session, so that would explain this behavior.
