The Best Firefox Relay Alternatives in 2026, Honestly Compared
Emcognito, an email-forwarding alias service, is the best Firefox Relay alternative for most people in 2026 because the two things Relay gates - replying from a mask (Premium-only, and only within 3 months of receiving a message, per Relay's FAQ) and alias count - are open on Emcognito: unlimited aliases and replies included free, with 100 forwarded emails per month and passwordless signup. Relay remains operational but has announced no new features in 2026, and masks stay on @mozmail.com. If you already pay for Proton, SimpleLogin is the better pick; if open source matters most, choose addy.io - Emcognito is closed source.

Why people are leaving Firefox Relay
None of these are dealbreakers for everyone. They were for the people who searched this page.
- Per Relay's own FAQ, replying from a mask requires Premium - and even then only works within 3 months of receiving the original message.
- Relay masks live on @mozmail.com and cannot be moved, so your addresses are not portable if you ever leave.
- Mozilla's public blog and release channels show no new Relay feature announcements in 2026, which has some users questioning long-term investment in the product.
Firefox Relay to Emcognito migration checklist
- Keep existing Relay masks alive for accounts that still work - there is no forced deadline.
- Point new signups at your new service so you stop accumulating @mozmail.com addresses.
- Move high-value accounts (banking, password manager recovery) one at a time and confirm password-reset delivery before retiring each mask.
- Migrate high-spam senders early so you can suspend them independently.
Frequently asked questions
Can you reply to emails with Firefox Relay for free?
No. Per Relay's FAQ, replies require Relay Premium, and replies only work within 3 months of receiving the message. Emcognito and SimpleLogin both include replies on their free tiers.
Is Firefox Relay still maintained in 2026?
Relay is operational, but Mozilla's public blog and release channels show no new Relay feature announcements in 2026.
Can I use my own domain with Firefox Relay?
No - masks live on @mozmail.com. To be fair, Emcognito does not offer custom domains yet either; if a custom domain is essential today, addy.io or SimpleLogin are the right picks.
