How disable kaffeine-mozilla plugin for specific websites?

[Christopher J. Bottaro]

First off, this dang plugin crashes Firefox after it tries to play the
media.  It doesn't crash right away, it crashes when you try to navigate
again after the media is done playing.

Anyways, almost every myspace page has music playing which causes this
plugin to launch kaffeine, which then results in an annoying crash.  Is
there any way to disable the plugin for specific websites?

Thanks.
