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.
