Flash site whitelisting not working ?

Good morning,

I would like to implement site whitelisting for FLASH but I cannot find the right combination of GPO settings.

I am tweaking two of them: - Activate Flash on websites left in "Not configured" - Allowed sites , enabled with a couple of domains on it. - Blocked sites, put * to block all by default.

I was expecting that only the two domains listed would be allowed to execute FLASH but the behavior was that for those two domains, the click to play is not shown. For any other site with flash i can simply click on the icon and enable flash for it. :/

Is that the intended behavior?

Using FF ESR 68.01 in W10 Enterprise

You're right. I should know since I wrote that.

There is no way to do what you are requesting (in any browser that I can find).

You can either globally disable/enable Flash or you can enable flash make it so it activates automatically on certain websites.

The blocklist is primarily for problematic sites.

To do this, set the default Flash policy to false (Default=false) and then add your domains to the Allow list.

Make sure to specify them with protocols:

http://domain1.com

You don't need to do anything to Blocked.

Thanks for the reply but I already tried that approach and it didnt work.

The description of the GPO setting is quite clear

https://getadmx.com/?Category=Firefox&Policy=Mozilla.Policies.Firefox::FlashPlugin_Default "If this policy is disabled, Flash is never activated on websites, even if they are in the specified in the Allow list."

So visiting a site included in the "Allow list" setting , Firefox shows that flash is allowed in that specific site but the flash is not actually running. :/
