This page can no longer be loaded from Firefox because firefox won't send a GET request for it. I verified this with Wireshark and proved it by comparing against Internet Explorer and Firefox Ver. 3.5.10, both of which work normally. Very strange bug, but it's real. Reproducible: Always Steps to Reproduce: 1.Try to request a page at some IP address, http://xxx.xxx.xxx.xxx/sysWebRTD.htm 2.Monitor HTTP GET requests with Wireshark 3.Observe that there is no GET request produced.
Do you get this only on your system or do you also tried it on other systems ? Do you use some kind of proxy and do you have some kind of Firewall installed ? Can you try a new profile ? http://support.mozilla.com/en-US/kb/Managing+profiles
