about:config

combinedfox user.js currently doesn't support Android. However, you can apply your preferences manually in about:config and UI in forks that don't disable access to about:config, such as Fennec F-Droid and IronFox. Note that not all preferences can be effectively changed in about:config. Read IronFox Documentation Why are certain preferences locked? before using about:config on Android. Read Fennec F-Droid and IronFox sections for more information.

Debug Menu

To enable Debug menu in Firefox for Android and its forks, go to Settings > About Firefox (or fork's name), and click Firefox's (or fork's) logo five times. Entries such as Install extension from file and Secret Settings will be shown in Settings.

App Store

The following stores can be used to install and update browsers on Android:

Firefox Profiles and Containers Alternative

Since Firefox profiles and containers currently don't support Android. You can use multiple browsers to achieve similar functionality. Besides different apps, work profile (in contrast to Personal Profile) can provide a second instance for each app. I recommend using Insular (com.oasisfeng.island.fdroid) from F-Droid or Shelter (net.typeblog.shelter) from F-Droid to manage work profile.

Fennec F-Droid

Fennec F-Droid browser is based on the latest Mozilla Firefox release. It has proprietary bits and telemetry removed, but still connects to various Mozilla services that can track users.

Refer to Fennec F-Droid on F-Droid, its build metadata, and repo of scripts and patches for the F-Droid flavor of Mozilla Fennec for more information.

IronFox

IronFox is a fork of Divested Computing Group's Mull Browser, based on Mozilla Firefox. Our goal is to continue the legacy of Mull by providing a free and open source, privacy and security-oriented web browser for daily use.

All users are HIGHLY recommended to take a look at our documentation, ESPECIALLY the Limitations and Frequently Asked Questions pages!

IronFox uses configs from Phoenix as well as IronFox-specific changes to harden and configure Gecko’s preferences. For more information on Phoenix’s features, please see the documentation here.

If adding extension redirects to download, go to IronFox settings, turn off Allow installation of add-ons and turn on again.

It sends DNT, and you can go to about:config and toggle privacy.donottrackheader.enabled to false to remove it. Refer to Do Not Track (DNT) and Global Privacy Control (GPC) section for more information.

Refer to IronFox documentation and repo for more information.
