Install the latest Firefox in Debian Buster

Last updated on 2021-03-04 Tagged under  # firefox  # debian  # linux

The stable release of Debian (currently Buster) packages the Firefox Extended Support Release (ESR). Tailered to the needs of large enterprises with backported security fixes, this version of the browser can lag several releases behind the current Firefox. If you want the latest and greatest Firefox, read on!

Let's go!

Download the latest version. Unpack ...

$ tar xvf firefox-*.tar.bz2

Move the unpacked folder into /opt and put a link to the firefox executable in your $PATH ...

$ sudo mv firefox /opt
$ sudo chown -R root:root /opt/firefox
$ sudo ln -s /opt/firefox/firefox /usr/local/bin/firefox

New firefox can co-exist with firefox-esr. I usually un-install it anyway ...

$ sudo apt purge firefox-esr

Debian will want to replace firefox-esr with another default browser (it doesn't track executables installed in /usr/local). I like to keep a copy of Chromium on my system, so I first install that package then remove firefox-esr ...

$ sudo apt install chromium
$ sudo apt purge firefox-esr

I use the dynamic menu launcher rofi to start my new Firefox.
