Group Policy: How Do I Whitelist Plugins Not Hosted By Mozilla?

Hi there,

I'm attempting to configure group policy in my organisation to only allow the install of selected Firefox plugins present in our whitelist. I am doing this via the ExtensionSettings policy within the Firefox templates v1.14

I have successfully made the default behavior to block plugins, using this string:

   "*": {
   "blocked_install_message": "Extension is not whitelisted. Please contact IT Support",
   "install_sources": ["https://addons.mozilla.org/"],
   "installation_mode": "blocked"
 }

I'm even able to successfully whitelist plugins on the mozilla addon page, example below:

   "support@lastpass.com": {
   "installation_mode": "allowed",
   "install_url": "https://addons.mozilla.org/en-US/firefox/addon/lastpass-password-manager/"
 }

My problem is I can't seem to whitelist any plugins that are installed from any source other than Mozilla. For example, Dashlane is only available via their website. I tried the following, but it still says blocked.

   "jetpack-extension@dashlane.com": {
   "installation_mode": "allowed",
   "install_url": "https://www.dashlane.com/en/"
 }

I have run into the same issue with another plugin, even when using the full URL of the .xpi file. I've played around with this for a good few hours, but nothing seems to work. Any advice?

Thanks in advance.

Did you try adding the Dashlane install page URL to your install_sources key?

You should remove install_sources and install_url.

If you are specifying exactly which addons you want installed by ID, it shouldn't matter where they come from.

And you don't need install_url because you are allowing the user to install.
