Yeah, Brave is actually built on Firefox code, if I remember correctly. Should provide you with adequate security out of the box. Though I'd personally also look into blocking Javascript.

Edit: I was wrong, it's built on Chromium :P

That's right, it's chromium. But the CEO of Brave was the creator of Javascript and co-founder of Firefox. A true master. I'm just waiting for them to release extensions support and I'll migrate to Brave. My main browser on Android is already Brave.
