I know Brave would have to create an agreement with Firefox to be added to the Search Engines list, but I think is worth it.
Right know you have to set it manually by following these steps:
- go to https://search.brave.com/
- right click the search bar
- click “Add “Brave Search””
But not many people are gonna do it. The average user, as it should be, just takes what is offered by default.
Because it’s the only option to Google Search and Bing to get information.
At the end of the day DuckDuckGo and similar are just Bing or Google frontends.
