Other Search Engines not sticking

Hello. Six months ago I posted a message here about my added search engines disappearing after I restart my browser. Specifically using search engine keywords is important to me. Because I really want Secure Browser to work for me, I waited and came back today. Added a new search engine. Closed and reopened. Search engine gone.

A respondent to my original post said he was reporting this issue to the developers. This is a basic function that’s accessible through the main settings menu. If it’s taking this long, is a fix hopeless? Or is there another fix I haven’t found?
