The Firefox Extended Support Release (ESR) browser is a robust and stable alternative to the standard Firefox browser, specifically designed for organizations such as businesses, enterprises, universities, and users who prefer long-term support (LTS) releases. Firefox ESR offers a range of benefits tailored to these users’ needs, including enhanced security, stability, and compatibility.
Some key advantages of Firefox ESR include the following:
- Extended Support: Firefox ESR provides long-term support, ensuring consistent stability and reliability over extended periods without frequent updates that may disrupt workflows.
- Security Updates: Although Firefox ESR does not receive feature updates as frequently as the standard Firefox browser, it is regularly updated with crucial security patches to protect users from potential threats.
- Compatibility: The slower update cycle of Firefox ESR ensures better compatibility with various web applications and extensions, reducing the likelihood of compatibility issues due to frequent browser updates.
- Centralized Management: Firefox ESR is tailored for easy deployment and centralized management across large organizations, streamlining the update process and reducing the administrative burden for IT departments.
The following guide will demonstrate how to install Firefox ESR on Ubuntu 22.04 Jammy Jellyfish or Ubuntu 20.04 Focal Fossa using the official Mozilla Launchpad PPA to ensure you receive the latest version of this reliable, LTS-focused browser.

In this step, you’ll install the necessary dependencies, import the GPG key, and add the Mozilla Team’s PPA for the latest Firefox ESR version.

- Generate Directories (if needed): If you haven’t previously imported a GPG key from the Ubuntu keyserver, you may need to create the required directories. Run the following command:
sudo gpg --list-keys
gpg: directory '/root/.gnupg' created gpg: keybox '/root/.gnupg/pubring.kbx' created gpg: /root/.gnupg/trustdb.gpg: trustdb created
If you encounter any issues, run this command and retry the subsequent steps.

gpg: keybox '/usr/share/keyrings/mozillateam.gpg' created gpg: key 9BDB3D89CE49EC21: public key "Launchpad PPA for Mozilla Team" imported gpg: Total number processed: 1 gpg: imported: 1
- Add Mozilla Team PPA: With the GPG key imported, add the Mozilla Team PPA containing the latest Firefox ESR version:
echo "deb [signed-by=/usr/share/keyrings/mozillateam.gpg] https://ppa.launchpadcontent.net/mozillateam/ppa/ubuntu $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/firefox-esr-stable.list
- Update Package Index: Before proceeding with the installation, run another package index update to reflect the newly imported PPA:
