I'm trying to get my Firefox installation to permanently disable private browsing mode, however, all information I can find is for the Snap version of Firefox, and not for the Flatpak version. How do I disable private browsing on my installation?

Looks good to me assuming that that is the correct Firefox installation folder. You can check this in about:support under "Application Basics -> Application Binary".

You can open the about:policies page to see if policies are active and if errors are reported.

The only way to disable PB mode is via a policies.json, I assume that this works the same on Flatpak and Snap.

Ive tried that, but no dice. I the put policies.json file in /usr/lib/firefox/distribution, and this is in the file: {

 "policies": {
   "DisablePrivateBrowsing": true
 }

}


Is there anything I did wrong?

Thank you! It wasn't under /usr/lib/firefox/distribution, and instead under /app/lib/firefox/firefox-bin
