## Description

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.

## Review summary

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.

- Helpful for privacy by reducing tracking.
- Positive overall sentiment and appreciation of Mozilla's initiative.

- 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).
