With 2001030804 on Win95, after several minutes of browing I begin to lose the ability to browse. I start receiving "Connection refused" messages. This affects all other browsers (IE, NS 4.76) so long as Mozilla remains running. IE reports that it can't browse DNS, which implies to me that perhaps Mozilla is failing to release TCP/IP resources. As soon as I exit Mozilla, everything returns to normal, no reboot required. I can restart Mozilla right away and browse for a few minutes and it will start reporting refused connections again.
Dupe of bug 71391.
