upgrading to 22.04 kills firefox

[Bob]

been using Kubuntu for many years and decided to upgrade from 20.04 to 
22.04 and got a new blank hard drive downloaded (on different computer) a 
live DVD and started the install, everything went as expected until I 
rebooted at the end and firefox was missing. in fact any access to the 
internet was missing.
    have heard "things" about "snap" but my first experience with it that I 
know of.   but have a fully functional, 22.04LTS on my new hard drive with 
no access to the internet via any means.  anyone got a workaround.  tried 
to download it to the harddrive from the web via the live DVD but it 
wouldn't write to the hard drive, and when I finally did get it written a 
reboot failed to load it.   (tried midori with same results)

hard to download something from web if one cannot access the web

????

thanks
