Je ne parle que le Français et donc il faut attendre la version avec Français

A service like this is necessary, so the idea is good although certainly not new: there are already dozens of temp email sites, and this is no better. The domain name gives it away immediately, so it's a matter of days for the spammers to add relay.firefox.com to the list of "invalid" email address they won't accept for signing up.

What we really need is temp addresses with a legit domain! For example, @mozillamail.com would be fine, as long as it provides real addresses too - just like, say, gmail. What matters is that the same domain hosts both temp and legit addresses, so the spammers can't tell temporary from legitimate. Yes, it's probably harder on the server. But short of that, such a service is nearly useless, as is the extension.

If/when done like this, users will want an easy way to reply to the spammer from the legit address via the temp address, without leaking the legit one. Now _that_ would be something that doesn't exist yet - at least not in an easy to use form. By "easy to use", I mean POP3/IMAP support and a transparent mechanism for the user.

No tiene una función para enviar información sobre errores del programa, ya que como es una fase beta seria lo recomendable para que llegasen lo mas rápido posible, ya que no tiene esa función diré por aquí, que tiene un error, que al recibir los correos en la bandeja de entrada, no se muestran los caracteres especiales.

I can not understand why I need to install addon to use Firefox Relay. It can be server-side solution, no need to install addons essentially. No explanation/justification was displayed when I registered myself to Firefox Relay. I felt like I am forced to install unnecessary addons. I trust Mozilla and I believe this addon does not collectt our user data. That is why I installed this addon. I will not if other service provider requests me to same thing.

As of today unable to sign up on kickresume. it says "looks like disposable address"

I am very interested in this application, and I have received an invitation email, but when I opened the extension, I found that I can’t access the relay.firefox.com website from China. Can developers support it in the future?

Can't even open relay.firefox.com to sign in...
I've already in the wait-list, even I've got invitation from Mozilla...
But I just can't open relay.firefox.com in China.

НЕ РАБОТАЕТ! Требует инвайт!!! И где его взять?!

I can't use it. It's installed in my browser, but when I sign in, it tells me I must visit the invite email first. I have no invite e-mail and I can't find a way to generate one. Completely frustrated!!!

i can't use this add-on from Cuba because google forbids it use, i always got next message: 403. That’s an error.

Your client does not have permission to get URL / from this server. That’s all we know.

i hope this change in future because i love firefox

Does not function. Sign in with Firefox account always brings me back to Sign in page.

Cannot reply from alias. I recommend using SimpleLogin instead. It's an open source email alias service.
