I agree with him 100%:

"Would be a nice extension but adding a commercial plug to my context menu is a total no-go and a reason to delete that extension at once!"

merci pour l'applcation

very bad, for my outlook.com address I received: We are currently unable to deliver emails to xxx@outlook.com. We received a soft "bounce message" from your email provider when we tried to forward the email to you. This can happen if Relay couldn't connect to your email provider or if your inbox is full. We'll try again on 01/17/2022 07:49.

My inbox is not full!

Would be a nice extension but adding a commercial plug to my context menu is a total no-go and a reason to delete that extension at once!

I really want to like this add-on but the first test message I tried, forwarded to my Yahoo mail account resulted in a message:
"We couldn't load this message retry". Retry yielded the same result.

impossible de répondre en retour au mail émetteur en utilisant
replies@relay.firefox.com pour exemple:

nom1.gmail.com ---> nom2(alias).mozmail.com---> nom3.free.fr
ça fonctionne mais

nom3.free.fr --->replies@relay.firefox.com---> nom1.gmail.com

ne fonctionne pas nom1.gmail.com ne reçoit rien en retour

This is a great extension and idea, I've always used 10minutemail and those types of services, but Relay needs some work, you can't choose what address it forwards the emails to. And something very simple, why not add your aliases directly to the window of the extension instead of making you open a whole new tab? So you can save a couple of clicks!
This does serve its purpose though, it is nice and handy.

trop neuf pour donner un avis

How can I SIMPLY report about sites that refused a Relay's alias ?
