If you are looking for a right click popup menu extension, this is the great one.
By the way, how to edit the popup text "Custom Menu"?

Lacking Wikipedia, Wish a update.

I got my context menu search back working with all my 47 already installed search engines.
Thanks! Great job!
I'm still waiting for the API patch so we won't need manual or external app to keep it up to date. But 'til there this extension is pretty satisfying.
