Or overlays.rdf/stylesheets.rdf in recent builds.

Correct, but very evil if applied to profile-installed addons:
you'll lose all other profile-installed addons and langpacks!

>From $profile/chrome/chrome.rdf, just delete all RDF-(XML-)items that
have an 'about' attribute "spiced" with the addon's name you want to kill.

Do the same for $profile/chrome/overlayinfo (or

In both cases, delete the XUL.mfasl for good measure, it'll get
recreated, too. ;-)

You may have profile related entries in your *app's*
installed-chrome.txt, but that is strictly no recommended way of
installing addons.
