First of all, it's opensource, it works, and all features are stable as the Stonehenge. My recommendation to everyone, who cares about privacy. I also pay for yearly subscription

Once you start using it, it becomes so natural that it just feels weird do give your true mail to any service at all.

Easy, secure and awesome

SimpleLogin is good, but the extension is pretty basic and bad UX.

Clicking the button makes an alias, but most webforms don't register the input so as soon as you click into the field it disapears. The extension doesn't bother to copy it to your clipboard, so most times you have to manually type it back in, or go to the SimpleLogin dashboard to re-copy it, which sort of defeats the point.

The simplelogin service is great! The extension could use a bunch of UX improvements; mostly in speed. It's just ... slow; and tiny; and very, very pink.
