What is Firefox Relay?
Firefox Relay from Mozilla creates email masks that forward messages to your real inbox, so you can sign up for sites without sharing your address. The free plan includes up to five masks and works through the website and browser extension, while Relay Premium adds unlimited masks, replies and phone masking in some countries.
Pros: what Firefox Relay does well
- Easy masks from the browser
- Run by Mozilla
- Turn off a mask in one click
Cons: where it falls short
- Free plan has only five masks
- Replies and phone masks need Premium
Who Firefox Relay is for
Anyone tired of spam after signing up for newsletters and shops.
Who can skip it
People who already use a password manager with built-in email aliases.
