Install Firefox 93 in Linux Systems

Ubuntu users will always get the latest version of Firefox via default Ubuntu’s update channel. But the upgrade isn’t yet available and if you are curious to try it, there is an official Mozilla PPA to test the new version of Firefox on Ubuntu and its derivatives.

Install Firefox on Ubuntu

$ sudo add-apt-repository ppa:mozillateam/firefox-next
$ sudo apt update && sudo apt upgrade
$ sudo apt install firefox

On other Linux distributions, you can install Firefox 93 stable from tarball sources in Debian and Red Hat-based distributions such as CentOS, Fedora, Rocky Linux, AlmaLinux, etc.

The download link for Mozilla Firefox tarballs can be found by accessing the below link.

The process of installing the latest version of Firefox from archive sources is similar for Ubuntu and CentOS desktop versions. To begin with, log in to your desktop and open a terminal console.

Then, issue the below commands in your terminal in order to download and install Firefox from tarball sources. The installation files will be placed in your distribution /opt directory.

For 32-Bit OS
$ cd /opt
$ sudo wget
$ sudo tar xfj firefox-93.0.tar.bz2
For 64-Bit OS
$ cd /opt
$ sudo wget
$ sudo tar xfj firefox-93.0.tar.bz2

After Firefox application files had been decompressed and installed to /opt/firefox/ system path, execute the below command to first launch the browser. The latest version of Firefox should open in your system.

$ /opt/firefox/firefox

Now close the firefox, and remove the old version of firefox and create a symbolic link to the new Firefox version as default.

$ sudo mv /usr/bin/firefox /usr/bin/firefoxold
$ sudo ln -s /opt/firefox/firefox /usr/bin/firefox

Launch Mozilla Firefox by navigating to Applications -> Internet menu where a new Firefox launcher should appear. In Ubuntu desktop just search for firefox in Activity dash.

After hitting on the shortcut icon, you should see the new Mozilla Quantum browser in action in your system.

Congratulations! You have successfully installed Firefox 93 browser from a tarball source file in Debian and RHEL/CentOS Linux distributions.

Note: You can also install Firefox with a package manager called ‘yum‘ or ‘dnf‘ for RHEL-based and ‘apt-get‘ or ‘apt‘ for Debian-based distributions, but the available version may be a little older.

$ sudo apt install firefox     [On Debian, Ubuntu and Mint]
$ sudo yum install firefox     [On RHEL/CentOS/Fedora and Rocky Linux/AlmaLinux]

  1. Mozilla 68.0 would not run on my Linux Mint 13 (yes, I know it is out of support but I run all apps in firejails and behind iptables). I believe it is from an older gtk release. Firefox goes into a constant loop of crash reporter, this even when disabling crash reporter by editing the application.ini file.

    How can I determine what libraries Firefox needs? Can I obtain the correct libraries, copy them to the same folder as Firefox, and still run it in a firejail?

  2. XPCOMGlueLoad error for file /var/tmp/firefox/ cannot open shared object file: No such file or directory
    Couldn’t load XPCOM.

    testing machine in VirtualBox/Vagrant, CentOs, ssh/xwindows forwarding :((

    • @Mirek,

      The latest Firefox 60 requires GTK 3.4 to run. The only way to install latest version of Firefox is to upgrade your Linux system.

      • yum provides “*/” # -> gtk3
        yum install gtk3

        So I have installed gtk3, xorg-x11-xauth, dejavu-lgc-sans-fonts.
        vagrant ssh (Vagrantfile: forwardconfig.ssh.forward_agent = true ; config.ssh.forward_x11 = true)
        or: ssh [email protected] -X -p 2222

        • @Mirek,

          That’s really great and thanks for sharing, let me give a try on my CentOS 6 box, last day me too facing same problem, but I didn’t tried it installing from YUM package manager thought latest Firefox needs upgraded GTK…:)

      • ssh -X # or:

        vagrant ssh
          where in Vagrantfile:
        yum install gtk3
        yum install xorg-x11-xauth
        yum install dejavu-lgc-sans-fonts
        # log out/in (exit/ssh)
        echo $DISPLAY   # will print: localhost:10.0

        We need firefox v58+ (at this time v52 from repo is not enough)

        cd /opt
        tar xfj firefox-60.0.tar.bz2
        ln -s /opt/firefox/firefox /usr/bin/firefox
        exit  # -> normal user
  3. If coming from Firefox ESR (Extended Support Release) then I think you might want to adjust your edits suggested above as follows:

    1) Do a global search and replace:

    $ sudo vi /usr/share/applications/firefox-quantum.desktop  
    :%s/Firefox ESR/Firefox Quantum/g

    >> 46 substitutions

    2) Include just one Exec line edited as follows:

    -> Exec=/usr/lib/firefox-esr/firefox-esr %u  
    +> Exec=/opt/firefox/firefox %u  

    3) Leave Icon=firefox-esr (otherwise it disappears from my cinnamon menu.) Perhaps someone else can tell me how to do this better.

    4) Simplify StartupWMClass:

    -> StartupWMClass=Firefox-ESR
    +> StartupWMClass=Firefox

    So far this seems to work for me. (Debian Stretch 9.2 / Cinnamon 3.2.7)


    • I just copied the icon from the quantum firefox directory to the “icon directory??”. (No idea if that’s what pixmaps actually is…)

      # cp /opt/firefox/browser/icons/mozicon.png /usr/share/pixmaps/
      -> Icon=firefox-esr
      +> Icon=mozicon128

      Thanks Howard for all the other info!
