Not all policies for the policies.json file work

So i started by installing the latest version of Firefox Quantum and then created a policies.json file within /usr/lib/firefox/distribution.

All seemed great adding the following: {

"policies": {
       "BlockAboutAddons": true,
       "BlockAboutConfig": true,
       "BlockAboutProfiles": true,
       "BlockAboutSupport": true

} }

But these seemed to be the only ones to actually do anything within Firefox. As soon as i added "DisplayMenuBar": false or "DisableDeveloperTools": true they didn't make any difference to the browser and therefore i was still able to access the menu bar and developer options.

Is anyone else having these issues? Is there a solution for these issues? Also does anyone know if we are able to remove aspects like the URL bar?

Thanks.

I don't think that "DisplayMenuBar" would Have effect to disable the menu bar (no disable in the policy name). This policy seems to be about whether the menu bar visible or hidden.

"DisableDeveloperTools": true should however disable all developer tools.

Did you check this with the Firefox (ESR) version from the Mozilla server since you posted with a Firefox version from the Ubuntu repositories?
