I used to use something called "Iron" which was just Chrome but without the whole tracking your every move aspect of it. Iron stopped working well for me, however, so now I just use Chrome. Dont like the personal NSA they have but it works well. On mobile I just use Samsung Internet. It works, so I'm not gonna even bother screwing with it.
Search engine wise, I used to use something called DuckDuckGo for the same reason I used Iron, and stopped using it for a similar reason. Now I just use Google.
