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.

    • @Shrinivas,

      Which version of glibc you have? if it’s 2.6, then it’s a bug that appears to have reemerged when Firefox runs under version glib 2.36. Try to update you Linux distributions and try installing again..

  4. followed the steps, when I run /usr/bin/firefox, nothing happened. I want to install ff29 on centOS6.4. Could you have a look?

    • @Constance,
      Could please share any error if you see on the screen? this article is for FF 41, not FF 29, but the same instructions works for FF 29 too..
