Update: 5 stars now. Developer quickly added an offset option. Great developer!

A nice replacement for the Context Search pop-up I was using with FF56. One thing that would make it nicer would be an offset option. Currently the auto-pop-up automatically appears over top of the text you had highlighted. The old Context Search plugin I used allowed you to offset the X and Y of the popup by a number of pixels so it would appear where you want it.

Other than that, the only other thing that sucks is Quantum's inability to let you easily add search engines to the search bar, which does limit the use of this plugin somewhat, though that's not the developer's fault.
