[Bug 1951646] Re: [snap] Firefox unable to load Security Device "p11-kit-trust.so" defined in /etc/firefox/policies/policies.json

[Olivier Tilloy]

That's indeed a snap-specific problem, and a confinement issue: the
application is not allowed to see /usr/lib/x86_64-linux-gnu/pkcs11/ on
the host system, the path is remapped to
/snap/core20/current/usr/lib/x86_64-linux-gnu/pkcs11/, which doesn't
exist.

I was able to work around the problem by downloading the p11-kit-modules
package for Ubuntu 20.04
(https://launchpad.net/ubuntu/focal/amd64/p11-kit-modules), unpacking it
in /var/snap/firefox/common/, and changing the path in
/etc/firefox/policies/policies.json to point there.

Not exactly easy, but it seems to do the job without requiring changes
to firefox or the snap itself.
