Comment:

 Code like the following can be used to enumerate the installed language
 add-ons:
 {{{
 let { AddonManager } =
 Cu.import("resource://gre/modules/AddonManager.jsm");

 AddonManager.getAddonsByTypes(["locale"], function(aList)
   {
     for (let addon of aList)
     {
       let uri = addon.getResourceURI("");
       dump(addon.id + ": name: \"" + addon.name + "\", uri: " + uri.spec +
 "\n");
     }
   });
 }}}

 The output from the above code looks like this:
 {{{
 langpack-es-ES at firefox.mozilla.org: name: "Español (España) Language
 Pack", uri: file:///Users/brade/Desktop/tb-
 esr38.app/TorBrowser/Data/Browser/profile.default/extensions/langpack-es-
 ES at firefox.mozilla.org.xpi
 langpack-da at firefox.mozilla.org: name: "Dansk (da) Language Pack", uri:
 file:///Users/brade/Desktop/tb-
 esr38.app/TorBrowser/Data/Browser/profile.default/extensions/langpack-
 da at firefox.mozilla.org.xpi
 langpack-de at firefox.mozilla.org: name: "Deutsch (DE) Language Pack", uri:
 file:///Users/brade/Desktop/tb-
 esr38.app/TorBrowser/Data/Browser/profile.default/extensions/langpack-
 de at firefox.mozilla.org.xpi
 }}}

 There does not seem to be an easy way to determine the locale (e.g., es-
 ES), so we may need to extract it from the id or uri. Similarly, we may
 need to obtain a language name to show to the user by parsing the name
 property (ugh). We can also include a locale-to-name lookup table in our
 code for the language packs we currently include in our packages.
