The concept is good but I'm not receiving some confirmation emails when I use the relay to subscribe on a website.

However, as some mentioned, it would be ideal for the widget to directly display the relay address and have the option to copy it.

Works fine.
One problem: it is very hard to copy emails from the manager if you have clipboardevents disabled, please auto select the email when pressing the copy button to CTRL+C it.
Also it would be better if there was no subdomain in the email.

This service is a great idea in principle and I hope it helps funding Firefox. But I already found sites that are blocking these alias email addresses, probably because it's too easy to simply block the relay.firefox.com domain. I'm not directly blaming Mozilla for this but hopefully new versions of the service will make it harder for sites to block the aliases.

Ottimo servizio! Da avere assolutamente per evitare lo spam in siti dove ti registri per prova

I like this extension, but it could be a bit better if you could choose which email address to forward emails to if you have any secondary addresses in your account.

Better yet, there could be the option to manually type the email address in, allowing you to choose whichever one you want. However, I understand if the developers don't want to add that feature because of the risk for abuse.

Also, if there is a way for Mozilla/Firefox Relay to tell me when a message that was supposed to be forwarded was blocked because it was too large, I'd like this extension/service even more.

I'm happy with how this extension is currently, but I still think it has some room for improvements.

Works for me. However it populates multiple entries in "Devices and Apps" section of Mozilla account. Probably as many as devices it's activated on. Makes no sense, as this is same service used across.

Grate add-on.. the only thing is the length of aliases.. some websites asking for shorter ones (like email address can't be longer than 25 characters) - any chance you can customize this a bit?? Thanks!!

Very cool addon, have been looking for something like this for some time, but it REALLY needs some way of having unlimited aliases. Maybe a pro version, maybe unlimited aliases with a custom domain, but unlimited aliases are really important because then you could create an alias for every website.

I already love this add-on and will likely use it more. The icon that shows up in email fields is so easy. My main gripe is that it takes a few minutes for the email to arrive, causing a moment of panic about whether it worked. Only one time did I experience that the relay email caused a purchase order form to malfunction. I trust Mozilla not to read the content of my email, but I would appreciate more information about the terms and processes of Amazon Simple Email Service. The link to their privacy policy from Mozilla's isn't really helpful enough, because I don't know what part is relevant for the service provision. I treat companies that "do" things with email with suspicion so Firefox Relay could differentiate itself more by emphasizing and explaining that it is indeed private and doesn't suck up or aggregate my private data (if that is indeed the case).

I find this service useful and the plugin nice. However, I experienced an issue and I found no place where to report it.
The issue: the plugin create a wrapper around the email field (class fx-relay-email-input-wrapper) with z-index of 99999999999999.
The label of that field was supposed to be over the field (z-index 100), but is actually hidden by the field itself (that normally has a z-index of 10) and this breaks the layout.
Thank you to consider this scenario in your tests.

The idea of a relay junkmail with option to enable/disable redirection is excellent!

However, I find the addon and the user experience to be near useless.

BEST UX practice:
1. Click on email field, addon suggests to input relay address.
2. Click on any alias, it gets submitted to field. Nice and easy.

Current flow:
1. Click email field, addons says "You have X aliases left", only "Manage" button available;
2. Click Manage, get redirected to Mozilla sign in page;
3. Sign in to Mozilla;
4. Manually copy alias from the list;
5. Go back to page with email field;
6. Manually paste the alias.

便利なんですが、転送されてきたメールで相手のメールアドレスがわからないのはどうしたものか...
また、エイリアスの管理画面で作成したエイリアスにメモなどを書き込めるとさらによいと思いました。今後エイリアス数上限が上がること期待してしまいます。
It's convenient. However, you can't know to know the email address of the person to whom the forwarded email is coming from. That's a complaint.
And I thought it would be even better if I could write memos and so on to the alias I created in the alias management screen. I hope the maximum number of aliases will be increased in the future.

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.

Please add the ability to enter existing relays into text boxes opposed to opening extension in order to copy an alias.
Otherwise no issues yet !

Firefox Relay Service and Unicode escape sequence.

That's what I get:
\u0417\u0434\u0440\u0430\u0432\u0441\u0442\u0432\u0443\u0439\u0442\u0435
It's "Hello" in Cyrillic.

--UPD--

It was "Body" of email. Google Mail.
Also, answer notification came to me directly to my main mail (not relay) and contains this:
We & #39 ;re
and
& quot; From & quot;, & quot;Subject & quot;, or & quot;Body & quot; of the email?

Idk is that google, mozilla or both.

A small downside to this addon, it should be possible from an email field to choose the temporary address already saved in the browser.

But I see that you can only create new addresses via the icon in the field.

if I want to take back a temporary email address already registered, I have to go in the address management to make a copy/paste.

FR: petit bémol a cette addon, il devrait-être possible a partir d'un champ email de choisir les adresse temporaire déja enregistrée dans le navigateur.

Or je constate que l'on ne peut que créer des nouvelles adresse via l'icone présente dans le champ.

si je souhaite reprendre une adresse email temporaire déja inscrite, il faut que j'aille dans la gestion des adresses pour faire un copié/collé.
