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.

Great idea. Unfortunately, the beta refuses to safe preferences (specifically the setting to stop replacing all email fields on websites). This makes it difficult-to-impossible to log in to some sites.

Love the idea here, but have a problem with encoded emails.
I receive emails in Hebrew, but the relayed emails appear Jibrish. I assume the relay does not work will for encoded languages.

Estensione quasi inutile... Problemi più gravi:
- Manca la possibilità di visualizzare le email bloccate
- Manca la possibilità di poter scrivere delle note vicino agli indirizzi (es. il sito dove è stato usato etc.)
- Non si può cambiare l'indirizzo email a cui vengono inviate le email

I wanted to try to register to 9gag.com using relay and the address is blocked.
I really didn't want to write a review yet as I couldn't play with it enough, but this is the only way to contact you.

Nice. I like the idea. I get the idea of having just a few while they're testing it, but I don't understand why the data on the site (i.e., your aliases) don't show up in the add-on. All we get it this crummy features slider and no way to turn it off or even make the tool usable, aside from trying to jam that huge logo into a small text field. I look forward to simple improvements.

I can't enter text in the email field on this page when the extension is installed. Apparently reviews are the only way to send feedback like this? https://public.viavid.com/player/index.php?id=140568

relay icon next to email field is in the tab navigation order between login and password field on some sites. Sadly this breaks my password manager. Please consider to rework this behavior.

Thx for the reply, I'm using Keepass 2.x But it should be the same with every password manager which uses Keyboard emulation.

Seems to be working fine so far. Except I am getting the developer tools box opening sporadically for no apparent reason.

I _want_ to like this, but there are some issues. In order for this service to be more useful than anonaddy, it needs to have the ability to create unlimited aliases with labels so that you can identify which are which.
Use Case: Using a different alias for each website so that you know which site leaked your email to other sites.

Being able to create an alias straight from the extension would be great as well. This would allow me to create an email alias with the firefox relay extension and the password with the lastpass extension. This pair would be a match made in heaven.

The ability to reply to emails that originated from Firefox Relay would also be a nice feature.

I'll be keeping an eye on this for future improvements. It definitely has potential.

Without the ability to reply using the Firefox relay alias, the very purpose to use Relay is moot!
I contacted a car dealership using one of my aliases. However, I had to reply using my own personal email, which got captured by the dealership, and I am now permanently entered in his distribution list.
So, what is the point?
--------------------------------------------------------------
I would like to have the option to create my own prefix email, using the @relay.firefox.com. Without the limitation of 5 aliases.
In this manner, I can control which email is being spammed, example:
I create an account with a new entity; I create the specific alias:
-Mynametag.newentity@relay.firefox.com
If I start to receive junk mail from "newentity", then I delete the alias.
I have done that for many years, unfortunately, it means that I need to create a new email address each time I enroll, which means my computer currently reads tens of email addresses.
So you should give the option to the user to create his own alias, and remove the limit of 5.

Edit on July 31st, 2020:

To avoid collisions, or similar prefixes, you can always have a validation running at creation time; I also add a string to make my alias unique, such as the date at which I create it:
20200731NewEntity@p6.firefox.com
This has two benefits: I can organize my email aliases list in chronological order, increasing or decreasing, and I always keep track of the date at which I created the alias.

BJs.com would not accept the new email alias.

Currently only allows 5 aliases (unlike Abine's DNT which is unlimited) and the button that appears in the email boxes overlaps the lastpass fill buttons.

idea seems nice...please invite me..
