HTTPS pages won't connect on Firefox + Debian Linux

[tresf]

A fresh install of Debian 11.6, QZ Tray does not work with Firefox or Chromium.

Chromium can be fixed using the following:

apt-get install libnss3-tools

... however Firefox doesn't work.

I believe the issue is that Debian ships with Firefox ESR, which uses different directory paths...

/usr/bin/distribution/policies.json:

{
  "policies": {
    "Certificates": {
      "Install": [
        "qz-tray.crt",
        "\/etc\/firefox\/policies\/qz-tray.crt"
      ]
    }
  }
}

... should be /etc/firefox-esr/policies/qz-tray.crt (and the file should be moved to the appropriate location).

Hmm... that doesn't work either...

So, it turns out that debian ships with firefox-esr but a script for firefox also exists at /usr/bin/firefox, so the policy is failing to install to the right location. Will work on a patch...
