Adds the Stract search engine to your firefox browser. In the URL bar you simply type
@stract search_query
This addon also enables you to set Stract as your default search engine, but it does not happen automatically.
There is currently no support for optics or similar things.
This project is based on firefox-yt-addon by atahabaki. I liked to have something similar for Stract also so this is why I created this fork.
Firefox has chrome_settings_overrides.search_provider to add your search engine to the omnibox. To learn more, take a look at MDN docs.
