set proxy username and password in firefox – Stack Overflow
I am able to set the proxy host and port using the preferences menu, but I see no option to set the username/password.
When I browse, I get a message, proxy is refusing connections. I am using squid proxy.
How do I do this?

I had the exact same problem as you had.
And finaly there is no way to add user and password to the default firefox proxy settings, so we need an addon to handle this for us.
In the current version FoxyProxy is doing this without any problems:
So try out the Add-On and you will solve this.

Open Firefox.
In the address bar, type about:config. A warning appears.
Click I’ll be careful. I promise! A variety of configuration options appears.
In the Filter box, type gotiate.
Double-click to toggle between true and false. The option must be set to false. (It seems counterintuitive, but you set it to false to make it work with the ISA proxy. )
