Step 1:
Remove the Firefox Snap by running the following command in a new Terminal window:
sudo snap remove firefox
Step 2:
Add the (Ubuntu) Mozilla team PPA to your list of software sources by running the following command in the same Terminal window:
sudo add-apt-repository ppa:mozillateam/ppa
Step 3:
Next, alter the Firefox package priority to ensure the PPA/deb/apt version of Firefox is preferred. This can be done using a slither of code from FosTips (copy and paste it whole, not line by line):
echo '
Package: *
Pin: release o=LP-PPA-mozillateam
Pin-Priority: 1001
' | sudo tee /etc/apt/preferences.d/mozilla-firefox
Step 4:
Since you’ll (hopefully) want future Firefox upgrades to be installed automatically, Balint Reczey shares a concise command on his blog that ensures it happens:
echo 'Unattended-Upgrade::Allowed-Origins:: "LP-PPA-mozillateam:${distro_codename}";' | sudo tee /etc/apt/apt.conf.d/51unattended-upgrades-firefox
Step 5:
Finally, install Firefox via apt by running this command:
sudo apt install firefox
As soon as the Firefox installation completes pop open the app launcher and click on the Firefox icon to launch a de-Snapped version you can pin to the Ubuntu dock.
