@kc2bez: I have been able to verify that privacybrowser is not working.
However it is not due to the apparmor user namespace restrictions.

I get the following segfault out of dmesg
[ 1591.466016] privacybrowser[7743]: segfault at 8 ip 000070bb4dd11ccc sp 00007ffd5c6587e0 error 4 in libQt5Core.so.5.15.12[70bb4da8e000+335000] likely on CPU 0 (core 0, socket 0)
[ 1591.466026] Code: ff ff ff 66 2e 0f 1f 84 00 00 00 00 00 90 f3 0f 1e fa 55 48 89 e5 41 57 41 56 41 55 41 54 53 48 81 ec 98 00 00 00 48 89 55 80 <48> 8b 5f 08 89 b5 7c ff ff ff 64 48 8b 04 25 28 00 00 00 48 89 45


I recommend opining a separate bug to track the issue.
