ubuntuzilla – apt with mozilla’s most recent versions

If you check your Ubuntu (or Mint)  after new releases of Firefox, you’ll figure it out that your browser is not updated yet. Other scenario is that you are using an Ubuntu-testing ISO image (beta or alpha) that is not a supported version, so you don’t have your browser updated yet. It’s worrying in some cases when Firefox fixes security issues. Ubuntu is not upgrading its repositories soon as Mozilla do upgrades.

That’s why you may want to install the latest version of Firefox from their own repository. Type the following commands in the terminal:

sudo add-apt-repository ppa:ubuntu-mozilla-security/ppa
sudo apt update
sudo apt install firefox

Do you wanna try the beta version?

You may also install the latest beta version of Firefox, you know it wont be completely finished.  There is a FTP with all the historical versions. You may download and install the latest beta version:


Now we have the Firefox version 56.0b4 ready to download.


In order to install this version of Firefox , type the following commands:

  • Extract the contents of the downloaded file:
tar xjf firefox-*.tar.bz2


  • Close Firefox if it’s open.
  • To start Firefox, run the firefox script in the firefox folder:



On many Linux distributions it is common to see a delay between a new release of Mozilla software, and the software showing up in the main distribution repositories. Depending on the distro policy, you might only see some security fix backports and not a full new release. It is frequently desirable to get more timely security updates for Mozilla software, or run the latest version, which may not be available in the repositories, due to the new features and improvements. This is where the Ubuntuzilla repository comes in. This repository tracks official Mozilla releases, and aims to push out the updated packages within a day or two of their release.

It host and APT repository with .deb repacks of the latest official release versions of Mozilla Firefox, Seamonkey and Thunderbird. The packages contain unmodified official Mozilla release binaries, which fact you are encouraged to verify by comparing the checksums of package contents with checksums of the contents of the official Mozilla tar.bz2 release archives.

The repository to add, if you’re adding it manually to your sources.list, is

deb http://downloads.sourceforge.net/project/ubuntuzilla/mozilla/apt all main
#Then add the package signing key to your keyring, by running the following command:
sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 2667CA5C

Install your desired package, with one of the following commands:

sudo apt-get update
sudo apt-get install firefox-mozilla-build
sudo apt-get install thunderbird-mozilla-build
sudo apt-get install seamonkey-mozilla-build
