This is on our list of policies to add, but it does not exist yet.

May we have any ETA when this will be available?

I'm hoping by EOL of Firefox 52 ESR.

Thanks for the response.

Can you confirm if this policy will be available for general firefox release OR it will be ESR specific only?

Appreciate your early response.

It will be on the RR as a machine policy. We're moving away from making things ESR only to making them machine policies.

Excellent, that's good to know if things are moving towards RR.

We have a large (15k+) firefox deployment with RR and its a challenge to replace it with ESR. Some of the policy items we need are only available for ESR release. Could you please confirm if below policy elements will also be working on RR? If yes, when can we expect?

1) URL whitelisting/blacklisting 2) Add-ons Management (whitelisting/blacklisting)

Appreciate your clear response on these items so that we could plan accordingly.

Yes. Both those policies will work on RR once we switch to only allowing them to be set via machine policies (not user policies).

Search will probably be the only thing we only allow on ESR.

allowing them to set via machine policies is something we can do currently or is a feature in development process? What is the ETA when we can expect to have it available all policies (except search) for RR?

Unfortunately this change didn't make 61 (tomorrow), but it should make Firefox 62.

do you mind telling when is 62 scheduled to be released?

Sorry about that. September 5.

It should contain a great deal of policy changes based on feedback.
