Hi wolfgang8741, thank you for the kind review and the feedback. For the subdomain aliases, they're really great because they're is no need to have the add-on actually generate them, you can easily create them on the fly. For example if you're on your favorite music streaming site you can just type in for the email music@yoursubdomain.mozmail.com and emails will start flowing through to that alias. Or if you're on a news site you could do newssite@yoursubdomain.mozmail.com. We created the subdomain feature for convenience in creating an alias, especially in person or when you're on a mobile app and don't have easy access to the add-on. We do encourage you to use random generated aliases as much as you can though, as a randomly generated alias has a lot more privacy benefits. Thank you!

Hi, we just released a new feature where you can use the context menu (right click on Windows, control click on macOS) and you should see an option to use existing aliases on this site or recent aliases. Try it out and let us know how that works.

Hi Jonah, we just shipped a fix yesterday. Can you ensure that you have the latest version of the add-on and let us know if you're still seeing issues. Thank you.

Hi DanD, thank you for the feedback! Exciting news, just today we released the functionality in the newest version of the add-on where you can sign back in with your existing aliases. Just open the context menu on any email address field (right click on Windows or Control-mouse click on macOS) and you'll see an option to sign in with recent aliases or existing aliases from this site. We hope you enjoy this improvement!
