After creating a fresh installation of Ubuntu 24.04, I installed DEB Firefox from APT by following Mozilla’s instructions from here. But I noticed that it was secretly replaced with Snap Firefox. I was able to verify this by checking the About Firefox page. This is the third time I noticed this.
It takes a little more than just adding a different repository to your package manager, you have to tell apt which to prefer:
echo ’
Package: *
Pin: origin packages.mozilla.org
Pin-Priority: 1000
Package: firefox*
Pin: release o=Ubuntu
Pin-Priority: -1’ | sudo tee /etc/apt/preferences.d/mozilla
True, but more often than not mozilla should have newer packages on their repository than any distribution. And the main problem still is that Ubuntu changed apt and threw snap in to the mix where it doesn’t belong.
