Mull
This is a privacy oriented and deblobbed web browser based on Mozilla Firefox technology. It enables many features upstreamed by the Tor Uplift project using preferences from the arkenfox-user.js project.
Due to lack of funding and only one person managing the entire project, DivestOS and its apps will not receive any further updates. This includes the Gecko-based browser Mull. https://divestos.org/pages/news#end

Comments and Reviews
always nice to have a fork of firefox oriented to privacy.
Doesn't work well because it speed in a lot of devices, chromium browsers, fennec or other Firefox browsers or WebKit browsers works a way more faster than this. Good work if you don't need speed but you want hide IP, improve fingerprinting resist, don't use about:config for disable telemetry because it doesn't have and use add-ons of Android Firefox. But because the speed of this browser (I and some friends test it in like 4 devices) I will still using Fennec, but great work.
A fork of Mull was created called IronFox.
It's like a hardened/privacy version of Firefox, similar to Fennec, except you don't really have to do any tweaking out of the box.
The Best Out of the box privacy hardened Firefox-based browser on Android. Absolutely amazing.
this works just like tor with better speed if you use "startpage anonymous view". it covers IP leaks, model, os, screen size and more. excellent job!
