Java Applet Helper
What is it?
The Java Applet Helper allows you more options in connecting to networks. Some networks are not yet configured to allow the Mibbit servers to connect to them. Others choose to block web based clients from connecting. More and more networks are joining Mibbit every day, but in the meantime, there's another option. If you run a server, and wish for people to use it without needing java (or any other plugin), see here.
How does it work?
When you select to use the Java Applet helper, a small Java Applet is loaded in your browser. You'll be prompted to allow it to operate. The Applet allows Mibbit (main client only at the moment) to connect directly from your box to the network rather than from the Mibbit IPs.
The Java Applet is only used for your own IRC connections (When you select it), and no other traffic.
Please be aware, that to use the Java Applet Helper, you must be able to connect out from your machine, to IRC networks, e.g., the IRC port must be allowed by any firewalls etc, and be able to run Java Applets.
