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.

Love not having to give my actual email address to garbage companies now, even my spam ones are worth more than their dirty tactics. The only improvement I could ask for is if you could make it so I can click the icon beside the address bar and directly copy aliases from there. Other than that, bang on.

Edit: 8 months on and you still have to open a new window to copy/paste your generated aliases. Come on devs, I know you can do better.

I love it, but some bugs are really annoying.
It ruins lot of input fields, even basic website such as Google. I can't wait for improvement, really nice extension. :)

it's really helps! and great! and just works! best product of mozilla

It used to work just fine, but now it stopped forwarding registration/email confirmation emails. Well, it says that it forwards them (the "Forwarded" field is incremented), but no emails arrive in my inbox. Surprisingly, pure-text emails from my other email addresses arrive normally.

Reply 1: I use ProtonMail. And yes, I did check spam and trash and every other folder - it's not there. Also, pure-text emails stopped getting forwarded too :(

Late edit: works perfectly fine now.

This extension is great if you want to subscribe to newsletters and then forget them or you don't want to give your main email to a website.

Like others have said - I love the idea, but just doesn't work for enough sites that I want it for (mostly social media or adult-oriented websites).

Update - doesn't work with Flickr
