It works. I don't know why Mozilla don't include Google search. In fact, I believe previous versions did include it, because on my older machine with an old installation of Thunderbird I can see Google in the drop-down list. One more nice thing, after installing this extension it's ok to remove it, the Google entry remains in the list. Nice!
