Install Firefox 81 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 81 on Ubuntu and its derivatives.

$ 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 81 stable from tarball sources in Debian and Red Hat-based distributions such as CentOSFedora, etc.

The process of installing the latest version of Firefox from archive sources is similar for Ubuntu and CentOS desktop version. 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-81.0.tar.bz2 
For 64-Bit OS
$ cd /opt
$ sudo wget
$ sudo tar xfj firefox-81.0.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

In order to create a quick launch icon in your desktop applications menu, issue the following commands in the terminal. First, change directory to /usr/share/application/ directory and create a new desktop application quick launcher based on firefox.desktop app launcher. The new launcher will be named mozilla-quantum.desktop.

$ cd /usr/share/applications/
$ sudo cp firefox.desktop firefox-quantum.desktop 

Afterward, open firefox-quantum.desktop file for editing and search and update the following lines.

Name=Firefox Quantum Web Browser
Exec=/opt/firefox/firefox %u
Exec=/opt/firefox/firefox -new-window
Exec=/opt/firefox/firefox -private-window

Save and close the file changes. Launch Mozilla Quantum by navigating to Applications -> Internet menu where a new Firefox Quantum launcher should appear. In Ubuntu desktop just search for quantum in Unity dash.

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