This isn't a typical disposable email service, therefore it shouldn't be added.

The free version of Firefox Relay cannot reply to incoming mail. This is essentially the same as a disposable address; I agree with the addition of Firefox Relay.

I believe Firefox Relay and AnonAddy should be on the list, but SimpleLogin should not.

I don't like the idea of adding Firefox relay. Disposable email addresses don't require a valid email address to be set-up, and they're accessible to everyone. This isn't the case for Firefox relay. Same for mailshld, or maskme by Abine.
