First impression: great application, I can finally use it to sign in some small sites or blogs that might have security concern. A little advice, I already hold multiple e-mail addresses for different use. If I could "customize the forwarding email address", that would be awesome. I could forward the spam&suspicious emails only to my "various special email addresses" and deal with them there, instead of the single important email address that I used for logging in to FireFox, which adds one more layer of protection. All in all, great service and great idea!

Can we change the forward email adress? I have a secondary email adress associated with firefox but I cant forward to it.

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?

me gusta como funciona

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.

I love using my custom domain to make up an alias anytime someone asks me for an alias "in real life"!

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 got the invitation but whenever I go on the relay site it tells me that I need to accept the invitation email - though I accidentally deleted it a while ago. Now I can't access the addon, nor add myself to the waiting list. :(

Edit 1: No way to respond to the dev response below, so adding it here.

Unfortunately I got the referral from a forum, and there's no way to recall where I received it from.

I don't know if the alias is completely randomly generated, but one great feature would be a partially customizable one like customAlias.generatedAlias@domain. Then it would be possible to identify the leaking site when starting receiving spam.

I would love to try this...please.

The idea by itself sounds amazing, could i get an invite?

Please send the invite.

Ready to use this extension. I've been a dedicated FF user since v.1, and a Netscape user from the beginning. Loyalty should be rewarded. :-) Slip me an invite, please.

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

How can I get an invitation ?
