Works perfectly every time- should be core to 3.0 Rated 5 out of 5 stars
Does just what it says, saving time & effort and without having to search page after page of search add-ons through the 'Firefox Add-ons: Search Engines' page.
Also allows you to save search engines for specific sites you use regularly, even if you're only looking for your favourite recipe at 'delia.com' !!!
