We have a linux time clock on our network that we were using firefox 4.x to access, after installing 5.0 we can get to the login page but it wont login. This is not a problem with the time clock because I can use internet explorer to loginon windows, but the mac admin needs firefox because they cant get internet explorer. I tried emptying the cache and cookies and that didn't fix it. i think some new security feature is blocking access, how do I find out what it is and fix it.
