#123 How to install?

[Amanda]

I downloaded this plugin along with the MRJ Plugin, however, I'm not sure how to install them. My computer tells me that there are no apps that can open them. I was going to use them to make a chat room on Deviant Art work, if that helps.

Here is what the Deviant Art FAQ says about this matter:
Mac/OSX
Firefox users with Java 1.4.2 or higher will need the Java Embedding Plugin found [here] (Will NOT work on 10.4)

I use Firefox version 14.0.1

I use a MacBook Pro running 10.6.8

Thanks!
