502 error in Firefox

Neiltupper — Sun, 09 Nov 2008 13:29:30 -0800

Firefox 3.0 502 error. Firefox 3.x, XP, "No proxy" in connection/settings
When I attempt to connect to the Aeroplan site I get a 502 error:
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /home.do.

Reason: Error reading from remote server

I can connect using IE6 on this computer or using Firefox on another (home) network computer. I'm not using a proxy server. I've searched Mozilla forums with no success so far

Is it safe to use proxy servers from public lists on the web?

I am outside the US but would like to watch some online TV episodes from US networks websites. I have found many lists of US-based proxy servers online that I could try, but I am concerned about security -- would using such a proxy server make me more vulnerable to viruses, worms, spam, and/or other such things? Many thanks.

Why am I getting a UCLA proxy page?

Why are random web pages rerouting me to a UCLA proxy server authentication log-in? Most recently I clicked on the link in this Mefi post and was redirected to this page. It's been happening at random times every so often with different web pages. I have no idea what is going on. I live in LA, but I do not live close UCLA at all, which shouldn't matter because I'm logged in to my own home WiFi. I'm not sure, I may have used it once in the past when I was on their campus but it's highly doubtful as I was never a student there. Is there some software on my computer that's doing this?
