More Firefox and ISA

The advice in the previous post about Firefox interacting badly with Microsoft ISA seems to be outdated.

The correct advice now:

1. Open (i.e. type) about:config in the location bar
2. Search for network.negotiate-auth.allow-proxies in the search bar
3. Double-click the line to set the value to false

You should now be able to enter your username/password combo once, have it remembered, and not be pestered with millions of pop-ups.
