How to list extensions installed in my Xul app?

In a Xul app, is there a high-level way to list the installed extensions?

Is the "Add-ons" w开发者_开发技巧indow available for easy use?

I'm trying to search in the firefox source, but it's a long way... if someone could give a shortcut I would be thankful... :)

Maybe something related to RDF? (not sure..)

Found it, just needed to open the url: chrome://mozapps/content/extensions/extensions.xul from my javascript.
