I did an automated update of my installed packages earlier today and it removed both firefox and thunderbird. I went to another machine and navigated to the pkg repository and sure enough for Freebsd 12.1 with amd64 architecture, both of these packages are gone. They are also both missing from the Freebsd 11 amd64 repository. I also checked the Freebsd 13 repository and I found them there but I have not upgraded to 13 yet. I am currently recompiling both of them from the ports directory. Any thoughts on what happeded?
