Facebook Container and Qubes

Before switching to Qubes I was using Facebook Container – Get this Extension for 🦊 Firefox (en-US) to limit Facebook invigilation. Now I’m only installed it in the browser in my Facebook Qube. My question is if this can be more effective when install also in other Qubes? I know only very little about facebook methods of tracking not logged users.

As I understand this only using “sandboxes” to separate browsing from browsing facebook, so facebook still can guess that You are You by compering some data? And it still be able to do that even if You are browsing from other VM on the same machine?

That’s something you have to decide for yourself.

Instead, I can propose you a way to automatically install the extension in every Firefox instance, without having to create a profile in a dvm-template (to avoid profile fingerprinting).

If you’re using firefox-esr create a policy.json file in /etc/firefox-esr/policies/policy.json in your TemplateVM, with the following content:

  "policies": {
    "Extensions": {
      "Install": [

If it doesn’t work, try copying it also to /usr/lib/firefox-esr/distribution/policy.json
