So far, so good.
Work as expected.
Easy setup.

Experiencing the same issues as a lot of other folks, I joined the waitlist over a month ago, finally got an invite email to install today and start using it, yet when I follow that link it prompts me to sign in and then asks me to join the waitlist... the one that I was already on. Makes no sense, very frustrating. Worth mentioning I'm in the USA, since it's only available here right now for beta. What gives, Firefox? :(

Edit: I figured it out so I figured I would update my review. Make sure you are logging in with the email address they sent the invite to. Apparently I use different emails for Firefox overall, and what I signed up for Relay waitlist. Don't even remember having a Firefox account for that email but, there you go. Hence the confusion. I think maybe the email could just give you a friendly reminder to do this, to avoid user error like mine (and maybe a few other folks).

This extension achieves all that it says, and works perfectly; from detecting signup pages to syncing with the dashboard (as well as the ability to label accounts).

There is however a very small issue in terms of ease of use, that would be auto filling previously used alias' from the popup menu created by the extension. There is only an option to "Create a new alias", and adding a list of previously created alias' would be helpful. This is a minor issue, and not something that affects the performance of the service itself.

In addition, another feature for the future could be the possibility of listing all the websites the email is used on.

Keep up the great work! I'm always hyped when Mozilla releases a new service because it never disappoints.

Works very well atm hope this doesn't get blocked to much :) Love the blocking feature to so you can block relays when you don´'t need mail from them

goodbye mailinator, firefox relay is my new friend ... some sites automatically block mailinator and other "dump mail" services... I thnnk that this will happen with this too :/

I like it very much...

this is really great feature. Thank you Firefox Team!
