Features & Capabilities

Firefox Relay helps you protect your primary email by generating unique, random aliases to use when signing up for online accounts, apps, or newsletters. These aliases forward messages to your real inbox, preventing unwanted emails and protecting your identity. If an alias starts receiving spam, you can block or delete it, stopping further messages without exposing your real email.

Upgrade to Firefox Relay Premium for unlimited aliases, the ability to send replies, and custom domain aliases that are easy to remember and share. With features like contextual menu integration and seamless browser support, Firefox Relay offers a simple yet powerful way to maintain your online privacy and reduce spam.

User Reviews

The reviews praise the extension's ease of use and its privacy-oriented goals, and show positive sentiment toward Mozilla's initiative. However, users report privacy/telemetry concerns, slow and buggy performance, and unreliable functionality (including sign-in and mail issues). There is also a recurring complaint about a five-alias limit with inconsistent behavior and about premium purchases being blocked in some regions. Overall, the add-on is valued but hindered by stability and privacy-related drawbacks.

Pros

Easy to use and intuitive extension.
Helpful for privacy by reducing tracking.
Positive overall sentiment and appreciation of Mozilla's initiative.

Cons

Privacy/telemetry concerns: extension can send data even when disabled and requests broad permissions.
Performance and reliability issues: slow, buggy, and some features fail (e.g., sign-in or mail delivery).
Alias/address limit of five with inconsistent behavior (some addresses may not work as expected).
Premium access is unavailable or restricted in certain regions (e.g., Turkey).

Is Firefox Relay Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Firefox Relay requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****
High ******* ****** ** *** ********* ******** ***********

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Firefox Relay has earned a good reputation and can be trusted.
