I like it very much...

this is really great feature. Thank you Firefox Team!

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

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.

Need an invite to get it working? Would be nice to get an ios version pushed. :D

This add-on is a great idea once its out of invitation only beta mode.

la idea por si sola es extraordinaria

Me parece una magnífica herramienta para mejorar el funcionamiento del navegador y añade mucho valor al mismo. Por favor, me gustaría recibir una invitación para instalarlo y probarlo. Gracias.

Nice Idea, Please send me an invitation ;)
