I can not log into any Stack Exchange sites while using the Firefox nightly build built today (11.01.2013). When I try to log in, it just says welcome you have been logged in please refresh the page, and when I do that, it says you have been logged in redirecting and it just redirects infinitely.

I already tried deleting all cookies and clearing the cache.

This worked on nightly builds pre 10.12.2013.

What is the explanation?
