Our proxy server requires authentication and FC3 users are complaining about firefox popping up strange looking authentication windows at random times (after they're already authenticated). As far as I can tell this happens when they visit sites using java. I found a suggestion that upgrading java would fix it but we have the latest installed (1.4.2_07). I could file this as a bugzilla report against firefox but I'm not sure if this is a firefox or a java problem. Anyone else seeing this problem? Thanks -- Ian
