How to disable Firefox add-ons in order to block to install temporary extensions. I am generating policies via Firefox Policy generator. { 

 "name": "myconfig",

 "configuration": {
   "arrayfields": {},
   "checkboxes": {
     "BlockAboutAddons": true,
     "BlockAboutConfig": true,
     "BlockAboutProfiles": true
   },

In order to disable the "temporary addon" button, you would need to disable the installation of any addons.

To do that, you can use ExtensionSettings. (https://mozilla.github.io/policy-templates/#extensionsettings)

It doesn't look like policy generator supports any complex stuff, so after you create the JSON, add a section that looks like this:

"ExtensionSettings": { 

 "*": {
   "installation_mode": "blocked"
 }

}
