Firefox seems to have caught Shoutitouts login on fire

Shoutitout has been having login issues as they stated in a blog post and several Shouts. We are not sure why they are having theses issues but it seems when people try to login if they are using Firefox they are redirected to thier profile page but are not logged in. Users have been complaining about this for a few days now and have only gotten limited information from Shoutitout. We have tried Shoutitout login on Firefox and had the same issue, so if emily or any Shoutitout staff is reading this post please tell us whats going.
