Hello Ladies and Gentlemen!
I want to change my Experience with the new Mozilla Repo and the Installation of Firefox. I used the Mozilla Guide to add it and it works good for me. I had no Problems and Errors.
The Preparation to have wget and create the Path /etc/apt/keyrings I didn't have to made because it was already in Zorin 17. So, I used the Commands and controled the Fingerprint and that's it. At the End I used the Command to change the Priority and that works good, too.
And now I have Firefox directly from Mozilla:
The only Thing that is a little bit ... disadvantageous: The Repo Files are in the sources.list.d Folder and in the keyrings Folder but in the ''Other Software'' List in ''Software & Updates'' there is no Entry for the Repo. When I use the Terminal it is listed there when I make a sudo apt update && sudo apt upgrade
Maybe it isn't in the List because I add the Repo with the Terminal and not with the Button at the Bottom of the List. It is just a little Thing but in common it works without Problems.
