2 Simple Ways to Install Firefox Quantum on Debian 9 Stretch

This tutorial will be showing you 2 ways you can use to install Firefox quantum on Debian 9 Stretch desktop. The default web browser, Firefox ESR, is sluggish on my Debian 9 Mate desktop, especially when there are many tabs opened. Furthermore, some websites and web applications may complain that Firefox ESR is out of date.

To address these two issues, you can choose to install Google Chrome on Debian 9 , or alternatively install Firefox quantum, which is touted by Mozilla as being twice as fast as Firefox was before and I feel it’s true after using it. On one of my Ubuntu systems, I have about 100 tabs opened in Firefox quantum. Guess what? It can still quickly load web pages! And I found myself using Firefox a lot more than using Google Chrome.

Starting with Firefox 57, Mozilla branded its open-source web browser as Firefox quantum to distinguish it from previous versions of Firefox. The name derives from project quantum, which aims to build the next-generation web engine for Firefox users.

This tutorial is going to show you how to install Firefox quantum by using snap packages and by using the tar archive from Mozilla. Some folks suggests installing Firefox quantum from Debian unstable (sid) repository or from a Ubuntu testing PPA. I do not recommend these two methods because they may cause instability.

Installing Firefox Quantum on Debian 9 via Snap

This is the easiest way. Starting with Debian 9 stretch, snapd is available from Debian repository, which means you can install snap packages from snap store. Mozilla released a Firefox snap package on March 19, 2018.

To install it, we need to first install snapd, which is easily accomplished with the following command in terminal.

sudo apt update

sudo apt install snapd

If you don’t have sudo, switch to root user by using this command:

su -

Then install Firefox quantum with:

sudo snap install firefox

After it’s installed, you can start it from your application menu. Choose Firefox web browser instead of Firefox ESR.

firefox quantum debian

Sometimes you need to log out and log back in to see the new entry in application menu. If you want a nice-looking theme for Firefox, you can easily find one from Firefox theme directory. Some people report that Firefox snap and the default firefox cannot run at the same time on Ubuntu. That’s because the binaries on Ubuntu are both named firefox. On Debian, the binary for Firefox ESR is named firefox-esr, while the binary for Firefox quantum is named firefox, so you can run Firefox quantum and Firefox ESR at the same time.

Snap packages are automatically checked for upgrade in the background, which is managed by snapd.refresh.service. You can check its status with:

systemctl status snapd.refresh.service

firefox quantum debian 9

It’s simply a systemd service for the following command.

sudo snap refresh

To list available update for snap packages, run

sudo snap refresh --list

If there is updated package available for Firefox, you can run the following command to upgrade Firefox quantum.

sudo snap refresh firefox

If you want to remove Firefox quantum, run:

sudo snap remove firefox

Installing Firefox Quantum on Debian 9 Stretch via Upstream Tar Archive

Mozilla provides a traditional tar archive for Linux users. You can download it from mozilla.org. If you prefer to use terminal, then run the following command to download it in terminal.

wget https://download-installer.cdn.mozilla.net/pub/firefox/releases/59.0.2/linux-x86_64/en-US/firefox-59.0.2.tar.bz2

Then extract the compressed archive with:

tar xvf firefox-59.0.2.tar.bz2

A new firefox directory will be created. To keep the file system tidy and clean, we move this directory to the /opt/ directory, which is traditionally used to store third-party applications.

sudo mv firefox/ /opt/

Then we can start firefox browser by using this command:

/opt/firefox/firefox

    I points from both options – I like the straight firefox, still having
    it integrated with a system package manager takes care of it’s self
    (although I’ve never used snap). Just like to add a suggestion when
    installing “manually”. To simplify the start command create a symbolic
    link in your path ie) cd /usr/local/sbin then ln -s /opt/firefox/firefox
    This may need tweaked to your system. A big thing
    missing from the .tar is a firefox.desktop file.
    https://wiki.debian.org/Firefox provides an example to create a simple
    one. Locate it in /usr/share/applications for system-wide or
    ~/.local/share/applications It puts firefox in menus and just helps
    provides system integration. (.desktop specs are from freedesktop.org)
