AFAIK fennec is the code name for mobile firefox when mozilla had the very good android app that supported extensions, about:config and sane tab/bookmark management, and fenix is when mozilla ended fennec and replaced it with the much worse and clunky android app around 2020 that's still the only official one today, right?

There's also a note from someone on Reddit [1]:
> Fennec is also F-Droid's firefox version. It differs from official ones by having proprietary bits and all telemetry removed as well as unlocked about:config at the moment.

(It also supports custom lists like Fennec and FF Nightly.)
