Sometimes this works, but not all the time. I have an outlook.com email address, and the email "bounced", so it didn't send. However, because it did this, it has temporarily suspended the email forwarding for more than a day! ALL of my aliases are blocked simply because ONE email did not send correctly! This is very frustrating, and it might be understandable (barely if at all) if the wait was like 10 minutes, but waiting more than a day is too much (32 hours). There also should be an option to view these emails that have "bounced", on the dashboard, or at least a "retry" button to attempt to send it again.

This service is useful and cool when it works, but it's just frustrating when it doesn't. Developers, please fix both the email "bouncing" problem AND shorten (or remove) the time that the service is disabled.

A nice idea, but you should explain that it's not completely free right at the beggining. It feels like you're mocking me when after reading everything I enter and realise I have 5 free tries and no more...

J'utilise Firefox relay depuis une semaine mais je ne reçois pas les messages sur les alias. Pas très pratique en cas de commande sur internet...Donc soit je n'ai pas compris comment ça marche soit ça ne marche pas.

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!"

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!

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

Ok, my computer is 6 years old, still, 15%+ cpu usage, all the time? Even when I'm just letting firefox run in BG? I haven't used the extension yet, but it hampered everything else.

l'extention .mozzilla ne fontionne sur aucun site

Buen concepto e intención. Sin embargo en los sitios donde más me interesaba mantener mi privacidad, no los pude usar porque no los aceptaban. Ya tienen registrado que mozmail.com se usa para ésto y no lo aceptan. Una pena. Gracias igualmente por el intento!

The relay tool is annoying at best. It breaks frequently where an email field will hover over a pop-up blocking the ability to fill in fields. I've noticed that Firefox is breaking web pages more often - mostly payment pages. Have to go to Chrome and MS Edge to complete transactions. Hoping I don't have to stop using Firefox but as more things break websites, the more likely the case.

I used Firefox Relay for several months on my Gmail account but then I found that although I could send emails to my friends at least three of them (possibly more) were unable to reply as the message they kept receiving was that the server was not compatable.

So ---- after much serching, I finally found (by mistake) the place where I could remove Firefox Relay. It was not easy to find this!!!

Now my friends can send emails to me again.

To answer the response from the developer: They were trying to send me emails to my regular Gmail address as they always had. They were not doing anything different from what they always had in sending me emails.

I am getting a 5.7.1 TLS required by recipient ERROR when I tried to use two of the relay email addresses - what's the problem please?

There aren't any directions it doesn't indicate if I need 1 or 5 I filled all out so I guessed. Again i'm left hanging no further instructions so I guessed. I seems the whole site is probably the same. Have someone from outside the building go through it. Each time I use an alias do I loose it. I'm hanging here should I just unload it?

Can't get it to work.

It's a great idea but is doesn't work. Clicking on the icon in the email address field doesn't produce an address. Wonder if it is being block by one of my other add-ons.
