For mobile, I’d recommend Mull instead of Iceraven
Pros:
- Just like Iceraven, a fork of Fenix
- incorporates the arkenfox user.js
- Doesn’t have “No warranties or guarantees of security or updates or even stability!” in its project description
Cons:
- APKs are only on FDroid
- awful name, no animal reference
- awful logo color scheme imo - magenta on turquoise is… an interesting choice
Here’s a probably somewhat biased but from quickly skimming over it not inaccurate browser comparison by the developer(s) of Mull:

At least the addons part has been mostly resolved - although not all addons are supported, Firefox mobile now has significantly more official addons than before:
