I use Firefox Focus on my mobile devices. It blocks trackers and you can easily delete your history and cookies.

Note: it's packaged on F-Droid as Firefox Klar, the German version, but the name is the only difference as far as I can tell.

The difference is that Mozilla's analytics are disabled by default in Klar to comply with German law.
