Autodetection is rather easy:
- Create a chrome URI for the package, e.g.
chrome://packagename/content/contents.rdf (the actual doesn't matter,
we're only interested in the first part)
- Get the real path via nsIChromeRegistry::convertChromeURL:
if it's a resource URI, it's in the application chrome; if it's file
URI, it's in the user profile. If we're paranoid, we could convert it
into a file URI and compare with the file URIs of both chrome directories.
(This method (of course) only works if the package isn't deinstalled
yet, because it makes use of the chrome.rdf information.)
