====== How to switch from snap to package in Ubuntu 22 ======
Since Ubuntu 22 they've decided to move Firefox to snap. Here's how to switch it back:

For Ubuntu 22.04, the empty Firefox Deb is pre-installed as a wrapper. You have to remove it via command:
  sudo apt remove --autoremove firefox
For Ubuntu 22.04 LTS, the [[https://launchpad.net/~mozillateam/+archive/ubuntu/ppa|“Mozilla Team” team PPA]] maintains the most recent Firefox packages in DEB. Add it:
  sudo add-apt-repository ppa:mozillateam/ppa
Set PPA Priority:
<code>
echo '
Package: firefox*
Pin: release o=LP-PPA-mozillateam
Pin-Priority: 501

Package: firefox*
Pin: release o=Ubuntu
Pin-Priority: -1
' | sudo tee /etc/apt/preferences.d/mozilla-firefox
</code>
Setup correct automatic updates, so that unattanded-upgrades don't overwrite our setup with snap:
  echo 'Unattended-Upgrade::Allowed-Origins:: "LP-PPA-mozillateam:${distro_codename}";' | sudo tee /etc/apt/apt.conf.d/51unattended-upgrades-firefox
Install Firefox from PPA:
  sudo apt install -t 'o=LP-PPA-mozillateam' firefox
