it's OK!

Please add on contextual menu or from toolbar icon, show all alias list and that I can choose some of them.

Really useful. Honestly a few tweaks away from being perfect. First and foremost would love to see the ability to click to copy alias from the drop down. Still a great extension and worthwhile.

It is extremely useful, but i would like if it is possible to name it to something that has a meaning, maybe a combination of two random words, or possibly giving the ability to name one of the aliases.

Also reply support will be appreciated.

valami, ...

Should be able to show existing alias and new alias form

Firefox Relay haven't been comfortable yet in Japan. I have experienced not receiving many emails from Japanese websites. So, I tested Firefox Relay on popular Japanese sites. Among 20 websites selected from SimilarWeb top websites ranking in Japan, I failed to sign up 11 Websites.

ベータは終わった？ように見えますが、まだ日本のメールへの対応は道半ばのように見えます。人気サイトの会員登録でテストしたところ半分以上で確認メールが届きませんでした。人気サイトでこれならば、リニューアルもなかなかできない普通のサイトではもっと多くの割合で失敗するのでは。
追記: ドコモメールもYahoo!メール (もちろんyahoo.co.jp の方です) もRelayアドレスに送信すると不通になりますね。

Unfortunately Firefox Relay uses Amazon Simple Email Service (Amazon SES). I despise Amazon and everything that they and Jeff Bezos stand for. Personally I do not do any business with Amazon and that includes Amazon AWS, and I wish that Firefox/Mozilla would find a better alternative for the core email service it is based on. Perhaps protonmail from Switzerland could provide this, which would be much better and ethically acceptable.

Regarding this add-on: The add-on works fine, but doesn't really add much useful functionality apart from being able to register an alias for relay addresses. The relay icon in any form field that accepts email is something that doesn't add anything for me, but it can be switched off. Instead of this add-on I prefer to use firefox lockwise for the usernames or email addreses and optionally the passwords.

Regarding Firefox Relay service: The number of 5 relay addresses is too little for my use case, also it would be good functionality that after switching off forwarding you'd be able to create a new relay address.

Some users have reported that some websites incorrectly assume these addresses to be temporary email. I believe this comes from the randomised hash in front of the @ sign. This could be circumvented by allowing manual entry of (part of) a username in a relay address.

I cannot disable that the icon is shown on each input field.

Why can't I just use an existing alias? Why only a button to create a new alias?

it's great but some features need to be added to make it 5 stars. Great job anyway!

Works great, hope for a "premium" option where I could choose my header, or have config options

la verdad no le encuentro tanta funcionalidad tenerla si solo es para es generarlos cuando puedes hacerlo en la pagina
