While Firefox comes pre-installed on Ubuntu, there may be instances where you need to install or reinstall it, whether due to a fresh installation, system upgrade, or personal preference.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation Firefox browser on a Ubuntu 18.04 Bionic Beaver server.


  • A server running one of the following operating systems: Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Mozilla Firefox on Ubuntu 18.04 LTS Bionic Beaver

Mozilla maintains an official Personal Package Archive (PPA) for Ubuntu, which provides more up-to-date versions of Firefox compared to the default Ubuntu repositories. This method is suitable for users who want to stay on the cutting edge while still benefiting from the convenience of package management.

Before adding the PPA, you need to import the Mozilla signing key to ensure package authenticity. Run the following command:

sudo apt-key adv --keyserver --recv-keys A6DCF7707EBC886F

sudo add-apt-repository "deb bionic main"

After adding the PPA, update the package index to make the new packages available:
