Firefox

Use Mozilla's PPA on Ubuntu

Nobody likes snap, and Mozilla maintains the latest stable Firefox in a PPA:

ppa:mozillateam/ppa

Start by removing the snap version that Ubuntu installs:

sudo snap remove firefox
sudo systemctl stop var-snap-firefox-common-host\\x2dhunspell.mount
sudo systemctl disable var-snap-firefox-common-host\\x2dhunspell.mount
sudo apt-get purge firefox

Then add the PPA: and install the mozilla firefox package:

sudo add-apt-repository ppa:mozillateam/ppa

Ubuntu will still prefer its package that installs firefox with snap, so create /etc/apt/preferences.d/mozilla-firefox:

Package: firefox*
Pin: release o=LP-PPA-mozillateam
Pin-Priority: 501

Package: firefox*
Pin: release o=Ubuntu
Pin-Priority: -1

And then apt should prefer the package from Mozilla after you update the cache:

amine ~ $ sudo apt update

amine ~ $ apt-cache policy firefox
firefox:
  Installed: (none)
  Candidate: 116.0.3+build2-0ubuntu0.23.04.1~mt1

        500 https://ppa.launchpadcontent.net/mozillateam/ppa/ubuntu lunar/main amd64 Packages

Now just install the firefox package:

sudo apt install firefox
