Basic Concepts

there are 3 storage area for chrome, sync, local, managed areas. the sync area will be synced with the cloud. managed area is read-only.

all your extension scripts share the same storage, including content scripts, they don't belong to their domain's localStorage.

Usage'key', function(data) {});["KEY1", "KEY2"], function(data) {});, function() {});  // data is key-value pair to store'key', function() {});["KEY1", "KEY2"], function() {}); {});
