Best for email masks from Mozilla
Firefox Relay hides your real address behind masks that forward to your inbox, and the free plan covers 5 masks with a browser extension. It can't reply from a mask, and the Premium plan shows no price and a waitlist button. Mozilla itself advises against masks for banks, doctors and lawyers.
Who Firefox Relay is for
- Fits if you want a throwaway address for a few sign-ups
- Works for people who already use Firefox and want masks built into it
Who Firefox Relay is not for
- Tight if you want more than 5 masks, as Premium shows no price and is waitlist only
- Not for you if you need to reply from a mask, as the free plan can't
- Watch out: Mozilla advises against masks for banks, doctors, lawyers and mail with attachments you must receive
- Watch out: Relay Premium is limited to listed countries, including the US, Canada, the UK and most of the EU
Why Firefox Relay gets a 2.2
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- CValue for moneyThe free plan is the only plan you can sign up for. Premium shows no price and a Join the Waitlist button, so there's no price on record.
- CFree plan and trialFree for 5 email masks, the extension and tracker removal. Five masks is a cap you'll hit, and the free plan can't reply from a mask.
- CFeaturesEmail masks, a browser extension and tracker removal. Gaps: replies and promo blocking sit on Premium, and phone masking has no price shown.
- BEase of useNo store rating on record. You install the extension and click to make a mask, with nothing else to set up.
- CPlatforms and integrationsWeb and a browser extension only, with no phone app, desktop app or integrations listed.

Keep Firefox Relay, or make your own?
Keep it
The plain part of Firefox Relay you could make: ad and tracker blocking. What surrounds it you could not. The 1 things listed below take a company, not a weekend.
That makes this kind of software worth paying for, not this one in particular: 45 of the 70 other email apps grade higher.
What you could make
- Ad and tracker blocking: an app builder makes this well.
What you could not
- Filters that read every message as it arrives.
What this rests on. Firefox Relay’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is Firefox Relay?
Firefox Relay gives you masked email addresses that forward to your true inbox, so you can sign up for sites without sharing it. A free account gets five masks. Mozilla's paid Relay Premium plans, which add unlimited masks and replies, are currently listed as a waitlist.
Worth knowing
- Premium and phone plans show no price and a Join the Waitlist button, so only the free plan can be signed up for.
- The free plan stops at 5 masks and cannot reply from a mask; masks go to your existing inbox.
- Mozilla advises against masks for banks, doctors, lawyers and mail with attachments you must receive.
- Relay Premium is limited to listed countries, including the US, Canada, the UK and most of the EU.
Key features
- Email masks
- Each mask forwards to your true address, and you can turn forwarding off for one mask without touching the rest.
- Browser extension
- An add-on creates a mask on a site's sign-up form. The homepage links the Firefox add-on, and masks can be made from the dashboard in other browsers.
- Tracker removal
- Common email trackers are stripped from forwarded mail, and this is included on the free plan.
- Promo blocking
- Premium can block promotional mail while still forwarding receipts and shipping notices. Blocking is not exact, so important mail can occasionally be caught.
- Anonymous replies
- Premium lets you reply to a forwarded email within 3 months of receiving it, and gives a custom mozmail.com mask domain.
- Phone masking
- A phone mask forwards calls and texts to your number and lets you reply to texts. The phone plan is a waitlist.
