I use a website for school that utilizes two factor authentication through a base site that then logins you in on that browser for a set amount of time. The problem I have is that on my Macbook pro the log in will not log me out of some sites and then it will log me out of other sites but then no longer load the log in screen on the laptop. Even if I do log in and clear all my cookies. I have all my security turned off so it isn't cross site cookies or a firewall blocking the site from loading. Please help. The site does work completely fine on my windows PC so I do not know if it is a mac issue or a Firefox issue
