Recommended:Firefox with the following extentions: Extensions
Download the Brave Browser for your phone. It is identical to Chrome except it automatically blocks ads and trackers. Plus it forces all websites to use https.
Google records everything you search. Use DuckDuckGo search instead (you can set it as your browser's default search). You can also install their browser extension. If you ever want to run a Google search just add "g!" before or after your DuckDuckGo search. There are plenty of other "bangs" that make DuckDuckGo searches better than Google!
