I mean to tell ya it was a lot of KDE programs, but, my installation was trashed yesterday, system would hang completely with no control except to power off yesterday, and I had to re-install.
I just typed sudo apt remove firefox and only firefox was displayed as being a candidate for removal.
At this point I have no explanation or reason as to why the previous condition existed.
Thanks for your reply and I wish I was able to provide the information you requested.
