Is Firefox Relay safe?

Clean risk

Generates email aliases that forward messages to your real address for account sign-ups and newsletters.

This extension lets you create unique, random email aliases and use them across websites instead of your real email address. You can block an alias to stop forwarded mail, delete aliases you no longer want, and access Relay features through browser menus and context menus. It uses browser storage for preferences and settings and has access to website content so it can offer its features across the web.

Where it sends data

Destinations our analysis observed Firefox Relay contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
