This article is optimized for Debian based Linux distributions, but most methods work in other Linux systems. We also tried Google Chrome, and that worked fine, too.This brief tutorial explains how to install the Firefox browser on Debian based Linux distributions.Īfter reading this tutorial you will learn different methods to get Firefox installed in your system. We can report that installing Chromium, then removing the built-in Firefox, installing Firefox-ESR from UbuntuZilla, and then removing Chromium left us with a fully working Firefox 91 with no apparent ill effects. Note, though, that installing actual Google Chrome won't satisfy the requirement. You can either let it install Epiphany, then install UbuntuZilla Firefox, then remove Epiphany again, or you can install the chromium package for the FOSS version of Google's browser first. This is because other pre-installed programs require a browser to be present. Installing Firefox-ESR threw up a different Debian glitch, though: you can't install UbuntuZilla's Firefox-ESR until you remove Debian's version – and if you try to do that, it will automatically try to install the GNOME Epiphany browser. This long-running third-party project packages the latest Mozilla builds of Firefox, Firefox-ESR, Thunderbird, and Seamonkey for Debian-derived distros.

One way round this that works on both Debian and Ubuntu is to use UbuntuZilla.
