Hi, For me, AppArmor blocks the signatures that are in a file, blocks the opening of http and https links in emails, blocks the opening of attachments like PDF.
The command "sudo aa-disable /etc/apparmor.d/usr.bin.thunderbird" solves these problems, but it is not the solution. The Thunderbird AppArmor profile needs to be fixed.
