I'm now on the premium subscription, and I'm using those email aliases everywhere I can!
It's very nice to have the ability to block & unblock per alias, and have the total number of emails sent on a specific alias to see if it's worth blocking or not. This saves me a ton of spam.

使い捨てメールアドレスを作成して、そのアドレスに送られてくるメールはFirefoxアカウントのメールアドレスに転送されてくるので便利です。

Bonne interface, bonne intégration, très pratique.
Nota pour debug (v2.4.5) : lorsque le module est activé, il m'est impossible de me connecter au site tgvinoui.sncf (avec une vraie adresse), car la page est systématiquement rechargée automatiquement dès que je saisie l'e-mail.

Most useful features are paid.

是否可以删除右键菜单？
Can I delete right click menu?

Very helpful, but it could be improved a lot if the masks were easily available from the toolbar icon for the times when the extension doesn't detect an email field.

When someone said wake up and smell the coffee they said this program doesn't need to access all your website data, I think its true it doesn't need this if its just relaying giving you a fake email address to use that hides your real email, why would it need access to all your websites? They collect data secretly from you who knows what they do with that data, or what if a hacker hacks Relay and they steal your data with it? What if we wanted to look at porn in privacy why should I share this data or payment services data? I swear humans are crazy and selfish they do anything for money.

Fix this I'll re-rate 5 stars thanks

Wake up and smell the coffee folks, any email alias service has NO NEED to access ALL or ANY of your firefox DATA!!!
