Mozilla launches Firefox Relay Premium

Firefox Relay Premium, a subscription-based version of Firefox Relay, is now available in select countries.

Firefox Relay is an email forwarding service that I reviewed back in 2020 when it first launched. It makes use of aliases that act as a proxy between a user's email address and sites and services on the Internet. The main idea is to block spam by using the alias email address and not the user's email address for communication.

Instead of leaving the "real" email address on a site, e.g. when leaving a comment, signing up for a service, or buying something, a user of Firefox Relay would use an email alias that is provided by the service for that. Firefox Release forwards emails to the user's email address automatically.

The concept that is behind Firefox Relay is not new. Disposable Email Services have offered similar functionality for a long time. Some allow the creation of throwaway email addresses, others support accounts and email forwarding just like Firefox Relay.

The free version off Firefox Relay requires a Mozilla Account. It allows users to create up to 5 email aliases, which are created randomly using the * hostname.

Firefox Relay Premium

Firefox Relay Premium is a commercial version of Firefox Relay. Like most commercial versions off services, it is offering more functionality to the user.

The three core differences compared to the free version of Firefox Relay are:

  • Unlimited aliases -- Aliases are not limited anymore, users of Firefox Relay Premium can create as many aliases as they require.
  • Custom email domains -- Users get the option to create a subdomain alias in the form when they sign-up for Firefox Relay Premium.
  • Replay to forwarded emails -- Firefox Relay Premium allows users to replay to emails using the Firefox Relay email address.

The introductory price is 0.99 Dollar, 0.99 Euro, 1.00 CHF. The service is available in the following regions at the time of writing: Canada, United States, United Kingdom, Malaysia, Singapore, New Zealand, Austria, Belgium, France, Germany, Ireland, the Netherlands, Spain and Switzerland).

Mozilla has not revealed when and by how much it will increase the price of the subscription.

Closing Words

The premium version of Firefox Relay adds much needed features to the email forwarding service. It is still limited, especially when it comes to custom domain use and other features, e.g. catch all email addresses or support for larger email attachments.

A service like Simple Login is available for $20 for the first year currently, and $30 thereafter, and it does support unlimited custom domains, which may be provided by the user, 5 subdomains, catch-all domain and support for PGP encryption.

Mozilla needs to add more features continuously to Firefox Relay Premium before it starts increasing the price of a subscription. Especially the one-custom domain limitation needs to be lifted, as services on the Internet could simply block from being used to interact with sites and services.

Now You: do you use a disposable email service / email forwarding service?

    Like these–

    “Forward Email” may work well for those who don’t regularly use disposable/forwarding services.

    No thanks. Probably will be discontinued like everything else they experimented with lately.

    They should stop doing monthly subscriptions, its burdensome for everyone. Do yearly only and make it cheaper (like 2 months free for every yearly sub). A package is simpler for everyone to support than a multitude of small charges.


    I’d rather Mozilla make a webhost or a blogging platform similar to
    Even if theyre paid-only, many would ditch their current scummy providers if mozilla only matched their hosting plans and prices. Theyre highly profitable anyway even for new entrants.

    Never god never let my mail go through MozCorp.

    Never for free, even less for money.

    Wouldn’t the obvious private solution involve using email providers that allow the use of aliases, instead of sending everything through a third-party, which even if it was trustworthy unlike MozCorp, would still be unneeded third-party exposure ?

      How much do the anti-Mozilla/Firefox trolls get paid, do you suppose? If it’s lucrative enough, I might be tempted. LoL!

        Payments are made in BAT tokens, so the main reward is your future chance to skyrocket to the moon in a Lambo!

    I like and

    Both are from Switzerland and that’s good because Switzerland is not a member of the 15.
    In all honesty do you think Mozilla Firefox relay is as secure as above mentioned by me?

      In all honesty, one should either provide proofs that Relay is insecure or mozilla will leak data of ordinary users to legitimated US (or non US, big 15) administration/law enforcment agencies. If mozilla provides those agencies based on law, then no objections here.

    Increasingly websites are no longer accepting disposable email addresses. The services I was using are now useless. Presumably, FF Relay will go the same way but, thank you. I will give it a try.
