Great idea, but txwo major flaws in the implementation:
- No way to quickly access existing / generate new email aliases from extension icon (it should display 1/ nb of aliases 2/ existing aliases 3/ generate new alias.)
- Relay icon on email fields clashes with password manager icon.

must have

Awesome, just one HUGE improvement suggestion. On the button to add a Relay email, add the option to select from the already created aliases. Having click on the extension, manage aliases, copy the wanted alias, then go back to the tab and paste it is unnecessarily complicated.

this good, i think you should add insert fast alias maybe same as login & password feature, why ? its make easy to user add firefox relay email, i use relay i have go to extension manage alias copy email relay this is not easy maybe you should add if that have from email in the right forms add button to add your alias, ya you can add 5 different alias. user can choose and fast add not go to manage alias and copy thanks

Hello, this extension make email form displayed as block, please fix that.
I've been looking for hours trying to make my website form shown in one line, I thought it was Firefox as browser's problem.
Make the relay icon position absolute would be nicer. So it doesn't really intervene with the interface.

50 aliases would be nicer.

relay.firefox.com fails DMARC on postfix MTA just like all other mails sent from firefox.com via amazonses service so this will only work for me until DMARC is enforced

Great idea. However, the first email I've received through this service seems to have been garbled due to encoding problems?

It would be great if whenever I click on the relay icon on the taskbar to display the list of aliases instead of clicking on the icon then clicking on manange my all aliases which will take me to a new tab just to copy my aliases.

A very good service. It is very easy to use. It works very quickly, I can hardly measure any delay.
An important necessary function would be to provide relay addresses in my overview with names or notes. When I get a spam email, I would like to know where I used that relay address. I could save that as a note, so I wouldn't have to search for the appropriate email in my archive.

Know this is probably not the Place (though believe it is relevant) but would the Developer mind responding to Review by: juan riccio posted nearby.

Not a user yet but am very interested in this. Tnx (3 Star for Middle of the Road, Had to install to review, Had to rate to Review,,,I think. Thank you Again)

A service like this is necessary, so the idea is good although certainly not new: there are already dozens of temp email sites, and this is no better. The domain name gives it away immediately, so it's a matter of days for the spammers to add relay.firefox.com to the list of "invalid" email address they won't accept for signing up.

What we really need is temp addresses with a legit domain! For example, @mozillamail.com would be fine, as long as it provides real addresses too - just like, say, gmail. What matters is that the same domain hosts both temp and legit addresses, so the spammers can't tell temporary from legitimate. Yes, it's probably harder on the server. But short of that, such a service is nearly useless, as is the extension.

If/when done like this, users will want an easy way to reply to the spammer from the legit address via the temp address, without leaking the legit one. Now _that_ would be something that doesn't exist yet - at least not in an easy to use form. By "easy to use", I mean POP3/IMAP support and a transparent mechanism for the user.
