UserAgent Browser Identification
Some websites refuse connection except from specific browsers. You can
generally convince your Mozilla browser to identify itself as
something else by adding something like:
user_pref("general.useragent.override", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)");
Plugins also exist to manage how the browser identifies itself to the server. The plugins will have names relating to user agent switching.
