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:
