Firefox add-on sdk uninstall hook

Question

I save some user data in simple-storage . When the user disables the add-in, I want to delete this user data. Is there some kind of event or something similar?

Answer 1

This will work in every file:

 require("sdk/system/unload").when(function(reason) { if (reason == "uninstall") { // do uninstall stuff.. } }); 

Answer 2

Try the following:

 exports.onUnload = function(reason) { //do stuff for unload here }
