Why is Firefox configured to use a proxy server on my computer ?
Recently while trying to sign on I received a message stating " proxy server refusing connection." I did not know that I had a proxy server.

Check the connection settings.
- Tools > Options > Advanced > Network : Connection > Settings

If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.

I also have this problem, and I tried the suggested solution of going into Tools>Options>Advanced>Network (tab)>Settings (button)>Select "No Proxy">Click OK.
This works, but is only a temporary fix for the current error message. There is no global solution. You must follow this path every time you get this message. It's annoying because it happens a lot.

You should only have to change this once, otherwise you have a problems with the prefs (possibly and extension makes the change or there is a user.js file in the Firefox profile folder).
If you do not keep changes after a restart or otherwise have problems with preferences, see:
I still do not know how to fix this. When I am on direct DSL connection I do not get the proxy message. When I am on my new wireless router I get these messages. I need to fix as I prefer wireless
