Better Than FF Built In Feature! Rated 5 out of 5 stars

Love It, Love It... FF's built-in 'add to search bar' doesn't allow you to add just any website. Use virtually any site's search box right from FF's search bar: well-known -to- obscure, highly specialized -to- 'mom and pop' sites.
An Invaluable Search Speed Dial —You Have It, You Can Search It. Immediately.
Efficiency and Speed —This is the addon.

This review is for a previous version of the add-on (2.0.1-signed).
