Extension Manager Extended is the perfect extension for developers who want to see another extension works.
Instead of looking up the id of the extension and then navigating all the way to the folder, just open the extension manager.
Next to all of the version numbers, the id is listed. Right click the extension, and you can even open the extension's folder right from Firefox.
