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.
From a security standpoint? Not even close. From a software-release validation requirement, not even in the same galaxy. If they look the same, it’s only due to Clarke’s law.
It’s a joke based of the fact that when you type apt install firefox on ubuntu, it will install the snap instead of the deb package, which is what you would expect when you use apt to install something.
In Ubuntu they are the same.
firefoxversion1:1snap1-0ubuntu5is a deb that literally runs the commandsnap install firefoxin the preinst script. Check line 77 infirefox-1snap1/debian/firefox.preinstin the source tarball: https://launchpad.net/ubuntu/+source/firefox/1:1snap1-0ubuntu5There’s no magic there.
