I have several. But really like Firefox Focus. Comes with tracking protection out of the box. Minimal settings. But still all you need. When you want plugins best Firefox Nightly.

I mostrly prefer Firefox for its independence. Since all other browsers are built on chromium and google seems to be on the road to give less and less access to its code.

When you have read, that Android will no longer be developed as opensource, but only release the code after a release.
