mplayer plugin for firefox
 

Currently Using: Slackware 10.2, with Kernel 2.6

Does anyone know how to setup the mplayer plugin for firefox with slackware?

Well, assuming you already have the mplayer plugin package/program installed correctly, I believe you just need to make sure you have a copy or link to mplayerplug-in.so in your firefox/plugins folder.

Unfortunately, I don't know exactly where either of these are found on a slack distro, but a find command should easily solve that problem.
