Setting Adobe Reader in policies.json

[Thane K. Sherrington]

Can I setup default handlers in the policies.json?  From reading, it looks like I can do something like:

{
    "policies": {
        "extensions": {
            "pdf": {
                "action": "useHelperApp",
                "ask": false,
                "handlers": [{
                    "name": "Adobe Acrobat",
                    "path": "C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader"
                }]
            }
        }
    }
}

But that doesn't seem to work, at least not in my larger policies.json that looks like this:

{
    "policies": {
        "ShowHomeButton": true,
        "DisableBuiltinPDFViewer": true,
        "DisplayBookmarksToolbar": true,
        "DisplayMenuBar": "always",
        "PSFjs": {
            "Enabled": false
            },
        "NetworkPrediction": true,
        "Proxy": {
            "AutoLogin": true,
            "Mode": "none",
            "SOCKSVersion": 4,
            "UseHTTPProxyForAllProtocols": true,
            "UseProxyForDNS": false
            },
        "SearchEngines": {
            "Default": "Google",
            "PreventInstalls": true
        },
        "extensions": {
            "pdf": {
                "action": "useHelperApp",
                "ask": false,
                "handlers": [{
                    "name": "Adobe Acrobat",
                    "path": "C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader"
                }]
            }
        }
    }
}

Any advice would be appreciated.

The extensions part should be under a Handlers policy:

{
  "policies": {
    "Handlers": {
      "extensions": {
        "pdf": {
          "action": "useHelperApp",
          "ask": false,
          "handlers": [{
            "name": "Adobe Acrobat",
            "path": "/usr/bin/acroread"
          }]
        }
      }
    }
  }
}

You also might need to escape those slashes.

Yes, it appears the slashes need to be escaped, but it's working for me now.
Is there a way to set Firefox to just open an extension with whatever Windows has as the default?  That would save worrying about the path.

For anyone else doing this, the block I ended up with was:

 
       "Handlers": {
            "extensions": {
                "pdf": {
                    "action": "useHelperApp",
                    "ask": false,
                    "handlers": [{
                        "name": "Adobe Acrobat",

                        "path": "C:\\Program Files (x86)\\Adobe\\Acrobat Reader DC\\Reader\\AcroRd32.exe"
                    }]

                }
            }

Try setting the action to useSystemDefault.

Hello!

I have noticed in the latest Firefox that I can't automatically deploy AdBlock-Plus extension for new FF profiles. I'm using policies.json.

This has been working for quite some time but not with FF 96 (authentication, homepage and override... values are dummy).

{
  "policies": {
    "Authentication": {
      "Delegated": [".home.lan", ".domain.com"],
      "NTLM": [".home.lan", ".domain.com"],
      "SPNEGO": [".home.lan", ".domain.com"],
      "AllowNonFQDN": {
        "NTLM": true,
        "SPNEGO": true
      }
    },
    "Certificates": {
      "ImportEnterpriseRoots": true
    },
    "Homepage": {
      "StartPage": "homepage",
      "URL": "https://www.domain.xy"
    },
    "OverrideFirstRunPage": "https://www.domain.xy",
    "OverridePostUpdatePage": "https://www.domain.xy",
    "SearchBar": "separate",
    "DisplayMenuBar": "default-on",
    "DisableTelemetry": true,
    "ShowHomeButton": true,
    "Proxy": {
      "AutoLogin": true,
      "Locked": true,
      "Mode": "autoDetect",
      "Passthrough": "<local>, 10.0.0.0/8",

      "SOCKSVersion": 4,
      "UseHTTPProxyForAllProtocols": true,
      "UseProxyForDNS": false
    },

    "ExtensionSettings": {
      "*": {
        "blocked_install_message": "Not allowed!",
        "install_sources": ["about:addons","https://addons.mozilla.org/"],
        "installation_mode": "allowed",
        "allowed_types": ["extension", "theme", "dictionary", "langpack" ]
      },
      "{d10d0bf8-f5b5-c8b4-a8b2-2b9879e08c5d}": {
         "install_url": "https://addons.mozilla.org/firefox/downloads/latest/adblock-plus/latest.xpi",
         "installation_mode": "normal_installed"
      }
    }
  }
}

When I start Firefox with a new profile, all other settings (homepage, authentication, certificates) are applied.

Any idea how can I solve this issue?

Kind regards,

Matjaz Pavel

This statement is incorrect and I'm not sure how it worked before:

"allowed_types": ["extension", "theme", "dictionary", "langpack"]

The correct type is locale not langpack.

You actually don't need this line at all since you are allowing all types.
