Aren't having any problems with Firefox . Have found that the latest versions of IE9 and Chrome are having a lot off issues with different websites. The issue seems to be with cookies in IE9 and the latest version of Chrome. I personally stay away from the latest versions of any web browser for at least 6 months.
