To install Firefox from the official Mozilla repository on Ubuntu 24.04, follow these steps:
1 Install the repository key:
wget -q https://packages.mozilla.org/apt/repo-signing-key.gpg -O- | gpg --dearmor | sudo tee /etc/apt/keyrings/packages.mozilla.org.gpg > /dev/null
2 Create a deb822-formatted .sources file in /etc/apt/sources.list.d/mozilla.sources with the following content:
Types: deb
URIs: https://packages.mozilla.org/apt
Suites: mozilla
Components: main
Signed-By: /etc/apt/keyrings/packages.mozilla.org.gpg
3 Set the apt repository priority by creating/editing the file /etc/apt/preferences.d/mozilla with the following content:
Package: firefox*
Pin: origin packages.mozilla.org
Pin-Priority: 1001
4 Allow unattended upgrades for the mozilla repository by creating/editing the file /etc/apt/apt.conf.d/51unattended-upgrades-firefox with the following content:
Unattended-Upgrade::Origins-Pattern { "archive=mozilla"; };
5 Remove the snap and apt installation of Firefox:
sudo snap remove firefox
sudo apt remove firefox
6 Update the package list:
sudo apt update
7 Install Firefox from the Mozilla repository:
sudo apt install firefox
8 (Optional) Install additional translations with the packages firefox-l10n-XX where XX is the language identifier (e.g. firefox-l10n-it for Italian).
sudo apt install firefox-l10n-XX
Prefer deb over snap (never suggest snap with apt):
cat <<EOF | sudo tee /etc/apt/preferences.d/nosnap.pref
# To prevent repository packages from triggering the installation of Snap,
# this file forbids snapd from being installed by APT.
# For more information: https://linuxmint-user-guide.readthedocs.io/en/latest/snap.html
Package: snapd
Pin: release a=*
Pin-Priority: -10
EOF
That is one command in the terminal. It adds a config file ( /etc/apt/preferences.d/nosnap.pref ) to stop Apt from suggesting or installing snaps.
