[Bug 2089141] Re: Opensc smart cards do not work in the snapped browsers

[Benjamin Davis]

I just finished following https://ubuntu.com/tutorials/enable-smart-cards-in-snapped-browsers#1-overview trying to get smart cards working in snapped Firefox and Chromium on my laptop (Mozilla Firefox 143.0, Chromium 139.0.7258.66 snap, Ubuntu 25.04) and was not able to get either application to authenticate via smart card. Admittedly, it's been a long time since I had to set up my browsers for smart card authentication, and there are a couple places I could have gotten off course, but I'm relatively confident I performed the following correctly:
- Installing to the browser the root CA from the authority which provided the certs on my SmartCard,
- installing OpenSC module to the browser,
- enabling pcscd on the snap,

Fairly unique to my set up: I had to hack my libccid to ignore my HP
smart card keyboard advertising as a pin-entry device, which is a broken
feature in that hardware.

I'm able to authenticate on the command line with `pkcs11-tool --slot 0
-l -t`. I just always find the "login" button in Firefox Device Manager
dialog disabled and smart card enabled websites complain I have provided
no certificate. Is there something obvious I have missed?
