  Yes.

• Describe the issue you encountered:
  Implement cookie prompts that would allow users to choose which sites' cookies they want to allow forever / for session, or deny.

Firefox does not have that core mechanism any longer (since version 44.0), and other browsers (except legacy IE) never had this in the first place.

Also, create relevant options in settings:

1. Accept all cookies
2. Block third-party cookies
3. Ask anytime (causes prompts)

Each cookie prompt should appear once for each site, since in Firefox, a prompt was thrown for each cookie (there were up to 77 per domain, IIRC).

Adding this feature should reduce the amount of issue requests wrt individual sites.

Bonus: Add information about the domain and suggestions (based on lists) —

1. Good domain with message in green backgorund,
2. questionable/unknown content with yellow background,
3. bad domain in red.

This all would most likely require a proper cookie manager.

Once implemented, release a video advertisement. It may be bad form to say bad things about competitors, but it pays off to say how awesome this new feature is that you recently added.
