Firefox 1.5 questionFollow

Okay, I downloaded 1.5 the other day, and I am having a strange issue. I am constantly getting a page that says "Connection to the server was reset while trying to load this page." This happens most of the time when I am on Alla, and seems to happen every single time I try to reply to a posting. It is not my internet connection; that is all fine. Once I get the page, I can immediatly reload and will usually then be able to load the page.

One thing the page does say is if you are in a network or behind a proxy to fix your settings, and I am in a network, but I am not sure what settings I would need to fix. The network just consists of a wireless router with security. This problem is quite annoying, any ideas?

Happens to me all the time as well. I think it's this sites problem rather than firefox.
