GM.getValue
From GreaseSpot Wiki
Description
This API method retrieves a value that was set with GM_setValue. If nothing was set and a default value is passed, it returns that default. Failing that, it returns undefined.
Values are saved in the Firefox preferences back end and can be manually changed by typing about:config in the address bar and searching for the preference name "greasemonkey.scriptvals.namespace/name.foo".
