[Bug 1930769] Re: When enabled, Firefox AppArmor profile prevents U2F devices from working

[Michael T]

Hi Don Rico!

This is actually fixed for me on 22.04

22.04 moved Firefox into snap, and snap has a whitelist of permitted U2F
tokens:
https://github.com/snapcore/snapd/blob/2.58.3/interfaces/builtin/u2f_devices.go#L43

That's a list of USB VID and PID, which you can find for your device
using the lsusb command. If your U2F device isn't on that list, you can
raise an MR like https://github.com/snapcore/snapd/pull/10642 to get it
enabled.

Some might debate the wisdom of the OS vendor maintaining a list of
blessed devices - but it is what it is.
