 Replying to [comment:20 cypherpunks]:
 > As for chrome vs. content and NoScript's focus, ok. But did you miss the
 part about Media Preview running a music player
 I did not. You don't seem to understand how that works.
 The element is an HTML5 audio, that's Firefox player. You can read the
 source for said player if you look in Firefox's source tree.
 > even though javascript was turned off completely in about:config?
 News flash: a huge part of Firefox is written in javascript. The
 about:config preference only disables it in content contexts, disabling
 everywhere would make the browser stop working.
 > I'm pretty sure the content wasn't php.
 No idea what you're trying to say here.
