Amazing. I can't believe this ancient extension doesn't have more users! Very simple; it uses the regular Firefox search site list (with the option to ignore some). I used other context search extensions for years, but this one is the best.

Finally !! simple, easy, light, non intrusive, and lets me choose what search engines i want to display in context menu. only been using for a few days but so far no bugs or issues.

PERFECTO !!

Custom Search with just 2 clicks! Perfect for translations, wiki lookups.
Should have been a feature of Firefox!
Search bar usage: decreased by 70%

Simple to use. I like how it matches with default Firefox style.
