Why not use Librewolf? Fork of Firefox, hardened and resists fingerprinting. Scores pretty damn well on https://privacytests.org and pairs well with Mull on Android.
AFAIK there are no actively developed Brave forks.

As a heads up, I believe Fennec is the old codebase for Firefox and it's no longer being actively maintained AFAIK.
Unless, of course, you're using the Fennec Browser built by F-Droid, which is confusingly based on the new Fenix codebase.
adbstands for "Android Debug Bridge" and it's an Android tool, not specific to Xiaomi.
