This is a reply to WXIE about a problem I wrote about yesterday. The document i am refering to can be found here. https://support.mozilla.org/en-US/kb/install-firefox-linux I am referencing Step 4 for Debian Trixie and Newer. I got over/thru those issues and when I ran apt update I found that the package was looking for Firefox was looking in a different place than where the previous steps place stuff. I am just comping back to Unix/Sun OS/Linux and 30 years working with a different OS. I hope this document will be updated after someone actually takes the steps. I will continue learning.
