[Sigi]

Addendum / Solution:

Use this policy file: /etc/firefox/policies/policies.json (FF update keeps settings)
Use this for current installation: /opt/firefox/distribution/policies.json (update overrides)

Hi everyone

On a MX desktop I need to disable "private browsing" in firefox.

I found some stuff like win registry "DisablePrivateBrowsing" and for Debian it should be in "/usr/lib/firefox/distribution" the policies.json like this:

Code: Select all

{
  "policies": {
    "DisablePrivateBrowsing": true
  }
}

But nether does this path exist on my MX-23.3, nor found this file on my file system.

How knows the solution, how to do this in MX? Thx!

Did you try a web search on "Linux Firefox no private browsing " or something line that?

You actually need to create that policies file in a completely different location than anything I have ever seen on the internet.

If you have an MX installed version of firefox, then the correct location where firefox is installed is:
/opt/firefox/distribution

And the policies file for what you want should look like this!

Code: Select all

{
    "policies": {
	"DisableAppUpdate": true,
	"DisablePrivateBrowsing": true
    }
}

( DisableAppUpdate is default for the distro )

Of course I did a search, I briefly described the results above, but for MX Linux I didn't find the path, well, here it is: /opt/firefox/distribution

Note: This policy file is provided with the package, so you'r adjustments would be overwritten
with next package upgrade.

Use this policy file: /etc/firefox/policies/policies.json
Create a new file with content:

Code: Select all

{
    "policies": {
    "DisableAppUpdate": true,
    "DisablePrivateBrowsing": true
    }
}

which won't be replaced during package upgrade,
so that your settings are retained and can only be changed with root privileges.
