On Firefox just add its search URL (https://stract.com/search?q=%s I think, it's somewhere above in this thread) to your list of search engines then set it as default. Idk about chrome

Thank you. I spent 5 minutes and could not find a way to add this URL in Firefox. I'm just saying, I like the search engine, I hope that they would like to have users. I would like to be one of those users but have no clue how to add them to my browser so until that's fixed they're basically a non-starter.
