Works pretty well (despite runtime.lastError; try putting your code in JQuery document ready). I wish it could be set to work on specific pages rather than whole domains.

Great but localhost raises error: "Unchecked runtime.lastError: Could not establish connection. Receiving end does not exist.". And please make it open source!
