This is an obviously useful add-on. I used to use "Context Search" but it is not being maintained and will be incompatible with FF 57+ so must find a replacement. "Selection Context Search" seems the best option but it needlessly complicates the method for adding search engines. FF already has a method for adding search engines via mycroftproject.com. I have a large set of search plugins that I have already curated and it would be daunting task to do this over again, especially by the method implemented in for this add-on.

Selection Context Search requires me to know the URL path for the search engine and gives me no hints as to how to find this info. Whereas, Context Search just used the already installed search plugins from MyCroft. And it is not even clear to me how I would add a search engine to Selection Context Search.

Why implement an entirely different and far less user friendly method of adding search engines when you can just use the search plugins that the user has already installed?

I hope the developer of this plugin will update this extension to use the existing search plugins. That is how it should work, logically. There is no need or value in implementing any other method of adding search engines. In fact, it detracts from the usability of the extension.
