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. I’ve gotten Firefox working but when I went to create a quick launch icon in my desktop applications menu I ran into “No such file or directory.” I used the commands “cd /usr/share/applications/” and then “sudo cp firefox.desktop firefox-quantum.desktop” like it stated but no luck. Can anyone help me because I have to run it through the terminal?

  2. I was happy to find an article like this judging only by the title, but I lost all faith in following the procedure described here when I read that you call Debian a “Ubuntu based Linux distribution”………

  3. Hi everyone,
    And thanks dear Ravi for producing this valuable resource.

    I have some difficulty going through the process of upgrading my firefox to 49.
    I followed the procedure above for my Fedora 21 (32-bit) but mistakenly extracted that from the Dolphin windows into my Desktop under firefox. And that is why I ended up messing my files. Now I cannot open my firefox by clicking on its icon with the error message:
    “KDEInit could not launch ‘firefox’:
    Could not find ‘firefox’ executable.”
    The only way I can access it is through command line:
    The only difference that I had compared to your case was that the old version was installed in /bin/firefox instead of /usr/bin/firefox.

    Now is there anyway to undo that or to correct the mess? Your help is greatly appreciated.

    • @Benjamin,

      Just delete the extracted Firefox directory from the Desktop, and follow the same instructions again to install Firefox as stated in this article.

  4. My current Firefox version is Mozilla Firefox 48.0. If i am watching some video stream then randomly Firefox crash. How can i fixed this issue? If I update to Firefox 49 then will this issue fixed or not?
    can i update without lost history, cookie and bookmark, etc..?

  5. After completing these steps and typing /usr/bin/firefox as root, “no such file or directory is returned” I retyped

    ln -s /full-path/firefox/firefox /usr/bin/firefox

    and the terminal confirmed that it already exists. /usr/bin/firefox-old still works though. Any idea what I did wrong? Was I not supposed to use full-path? Sorry, newbie here.

    • @Jess,

      You should be normal user to download and extract the latest version of Firefox and then become root to symlink it and then become normal user to start it..

    • Jess, when you typed it did you type /full-path/firefox/firefox? Or did you replace /full-path with the REAL path information for the directory.

      The command ‘pwd‘ (prints out your present working directory) will tell you where ever you are in the file system directories. So it the path was /home/thor/packages/firefox/firefox.

      You would type ln -s /home/thor/packages/firefox/firefox /usr/bin/firefox

      I believe the author expects you to understand that /full-path isn’t what you would literally type in. It is a placeholder for wherever you had unpacked the package on your system. So to get that you would type ‘pwd‘ in the same folder where your new firefox binary is located.

    • @Joe,

      Actually, the latest version of Firefox doesn’t provide any binary packages, they are available in source packages only..

  6. I love Firefox and it’s the only browser I use (on all OS: Linux, Windows, Mac, and even Android). However, after updating to 46, it stops working on my Linux computer at work due to the issue. My admin said he can’t install because my Ubuntu is too old. I don’t want to re-install my Linux. Everything was perfect with Firefox (well, except for some crashes) before the update. Can anyone find some solution so I can continue to use Firefox?

    • @Luke,

      Unfortunately, it isn’t possible to update the on older Ubuntu version, if you really want to use most recent version of Firefox, you should consider upgrading your OS

      • I have the same issue as OP. I just tried Firefox AppImage and it will throw an error:

        XPCOMGlueLoad error for file /tmp/.mount_FirefoThhphp/usr/bin/ cannot open shared object file: No such file or directory
        Couldn’t load XPCOM.

        So no, it doesn’t work.

        Couldn’t found any way to get in touch with “probono” to ask about this either… So we’re stuck.

        • @Blablabla,

          Try installing from Firefox PPA, if you are using Debian or Ubuntu, else download and extract Firefox tar file, and run it directly.

          • You clearly didn’t read OP. I’m facing the same issue, can’t install GTK+3 nor Firefox Quantum, hence to use it we *need* a “portable” version. Obviously that won’t run because we can’t have GTK+.

            Plus, on an email exchange with “Probono” (AppImage master mind) he basically stated that “98% of Linux computers have GTK+installed, and since we support AppImage packagers but not end users, screw you because I won’t help”.

          • @Blablabla,

            I read it your comment, thats why I suggested you to install from PPA, as it install all required dependencies automatically. Yes, most of the todays Linux computers have GTK+ installed default.
