Hi, I have more info. The same problem, I can't open links from thunderbird.
I used to be workaround it by put the /etc/apparmor.d/usr.bin.thunderbird in complain mode. But this not work anymore. Now I have to disable de /etc/apparmor.d/usr.bin.thunderbird profile with sudo aa-disable /etc/apparmor.d/usr.bin.thunderbird sep 15 14:36:55 gsus-v110-14ast audit[9930]: AVC apparmor="DENIED" operation="file_mmap" profile="thunderbird//sanitized_helper" name="/opt/waterfox/waterfox" pid=9930 comm="waterfox" requested_mask="m" denied_mask="m" fsuid=1000 ouid=0 sep 15 14:36:55 gsus-v110-14ast kernel: audit: type=1400 audit(1600191415.454:368): apparmor="DENIED" operation="file_mmap" profile="thunderbird//sanitized_helper" name="/opt/waterfox/waterfox" pid=9930 comm="waterfox" requested_mask="m" denied_mask="m" fsuid=1000 ouid=0 sep 15 14:36:55 gsus-v110-14ast audit[9932]: AVC apparmor="DENIED" operation="file_mmap" profile="thunderbird//sanitized_helper" name="/opt/waterfox/waterfox" pid=9932 comm="waterfox" requested_mask="m" denied_mask="m" fsuid=1000 ouid=0 sep 15 14:36:55 gsus-v110-14ast kernel: audit: type=1400 audit(1600191415.556:369): apparmor="DENIED" operation="file_mmap" profile="thunderbird//sanitized_helper" name="/opt/waterfox/waterfox" pid=9932 comm="waterfox" requested_mask="m" denied_mask="m" fsuid=1000 ouid=0 sep 15 14:36:55 gsus-v110-14ast audit[9934]: AVC apparmor="DENIED" operation="file_mmap" profile="thunderbird//sanitized_helper" name="/opt/waterfox/waterfox" pid=9934 comm="waterfox" requested_mask="m" denied_mask="m" fsuid=1000 ouid=0 sep 15 14:36:55 gsus-v110-14ast kernel: audit: type=1400 audit(1600191415.684:370): apparmor="DENIED" operation="file_mmap" profile="thunderbird//sanitized_helper" name="/opt/waterfox/waterfox" pid=9934 comm="waterfox" requested_mask="m" denied_mask="m" fsuid=1000 ouid=0 sep 15 14:36:55 gsus-v110-14ast audit[9937]: AVC apparmor="DENIED" operation="file_mmap" profile="thunderbird//sanitized_helper" name="/opt/waterfox/waterfox" pid=9937 comm="waterfox" requested_mask="m" denied_mask="m" fsuid=1000 ouid=0 sep 15 14:36:55 gsus-v110-14ast kernel: audit: type=1400 audit(1600191415.846:371): apparmor="DENIED" operation="file_mmap" profile="thunderbird//sanitized_helper" name="/opt/waterfox/waterfox" pid=9937 comm="waterfox" requested_mask="m" denied_mask="m" fsuid=1000 ouid=0 sep 15 14:36:56 gsus-v110-14ast audit[9939]: AVC apparmor="DENIED" operation="file_mmap" profile="thunderbird//sanitized_helper" name="/opt/waterfox/waterfox" pid=9939 comm="waterfox" requested_mask="m" denied_mask="m" fsuid=1000 ouid=0 sep 15 14:36:56 gsus-v110-14ast kernel: audit: type=1400 audit(1600191416.234:372): apparmor="DENIED" operation="file_mmap" profile="thunderbird//sanitized_helper" name="/opt/waterfox/waterfox" pid=9939 comm="waterfox" requested_mask="m" denied_mask="m" fsuid=1000 ouid=0 Sl2 Jesus Eguiluz Ingeniero Electrónico.
