Site Permissions (popup exceptions, etc) (JSON)

List of site permissions (popup exceptions, etc). Must be in single-line "minified" JSON format. See example at bottom.

NOTE! If this policy is defined here, all inherited "site permissions" from a parent policy are lost. To keep all settings from an inherited policy, combine/merge the individual site permissions from the parent policy into this policy. For example, if you are adding one new site preference here and a parent policy already has three other site permissions that you want to retain, define this policy with all four site permissions in it.

Below is an example of multi-line JSON settings. See conversion details below.

"": { // *these comments need to be removed*
"cookie": 1, // allow cookies
"install": 1, // allow installing add-ons
"plugins": 1 // allow plugins
"popup": 1, // allow popups
"": {
"popup": 2 // disallow popups

Below is an example of the above settings converted to single-line "minified" format and prefixed with "JSON:". This format is required for this policy setting.


You can use various JSON-formatting websites for validation and conversion, such as:
