Ever tried to go on the IRC with Firefox? But Firefox doesn't open the protocol of IRC. So what you need is a Firefox Plug-in, called ChatZilla.
1. First download the Plug-in. https://addons.mozilla.org/en-US/firefox/addon/16
2. Install it into Firefox [Firefox restart might be required].
3. Now you can go to any IRC addresses.
irc://irc.mpgh.net/MPGH
4. You can now celebrate by dancing.
Thats cool, perfect tutorial for people who dont know how to do that
