Prism is a sandboxed web-app tool, essentially it is Firefox for one application at a time. It’s been a while since I played with it, so I’m taking another look.
This should work on any Debian based system really, but I did it on Sidux. Here’s how I installed the latest version on my machine.
# wget http://prism.mozilla.com/downloads/1.0b1/prism-1.0b1.en-US.linux-i686.tar.bz2 --2010-01-26 16:01:08-- http://prism.mozilla.com/downloads/1.0b1/prism-1.0b1.en-US.linux-i686.tar.bz2 Resolving prism.mozilla.com... 126.96.36.199 Connecting to prism.mozilla.com|188.8.131.52|:80... connected.

At that point it should be in your path and ready to invoke!
