I have recently added a new search engine in Firefox Focus, but I find out that something may be wrong with the URL after trying a few searches. I went to the search engine settings page in the app, only to find out that I cannot edit search engines which I have already saved. This means that to test different URLs, I would have to delete the search engine, paste the url again, edit it, name the search engine in case it works that time, and then go back and test if it works. This really shouldn’t be the hassle that it is right now.
