Beaker Browser (“An experimental peer-to-peer Web browser.”)

Brave (I highly recommend this browser.  Brave utilizes a rare browser feature that prevents “bounce tracking.”  They also employ a new feature called De-AMP that allows users a browsing experience free of Google’s controversial AMP technology.)

Bromite (only available for Android Lollipop v5.0, API level 21 and above; Bromite is a fork/modified copy of web browser Chrome.)
