Rated 3 out of 5 stars
This review is for a previous version of the add-on (1.6).
Sadly this disables Context Search provided by https://addons.mozilla.org/en-US/firefox/addon/240 When I say disable, no search appears at all in a new tab. Nothing.
Good idea though if I can get it to work with your excellent Add To Search Bar https://addons.mozilla.org/en-US/firefox/addon/3682
I only use Search from within the context menu as it's VERY quick.
