In the logs I see concerning my apparmor profile for firefox:

apparmor="DENIED" operation="open" parent=5592 profile="/usr/lib64/firefox/firefox{" name=2F6D6E742F6D79696E7465726E65742F6D797468756E646572626972642D64617669642F2E7468756E646572626972642F4372617368205265706F7274732F496E7374616C6C54696D6532303133313230373030 pid=5593 comm="thunderbird-bin" requested_mask="r" denied_mask="r" fsuid=1000 ouid=1000

This doesn't give me a hind as to what file was access denied by firefox since it is only a long string of characters. Anyone has a clue to what this refers?
