first time rating something whatsoever. worth it.

Positive: Supports sidebar. Adheres to system theme by switching between light and dark. Negative: Requires API key generation rather than OAuth login.

Saves time. Has worked great in FireFox since my first use, now it been about 10 months and still works great. Easy to manage alias's.
Thanks.

The best option, with more features and it isn't geo-resticted, unlike Relay

A great extension for a great service. It is simple which is exactly what I need. Just plug it in and load your aliases. My only complain is that aliases take up to ~5 seconds to load.

Very handy dashboard of generated email aliases.

Free subscription even better than firefox relay's one

It does work with Hotmail/Outlook, unlike that other anonymous email extension.

A feature I'd like to see is, like what that other add-on does, insert the domain name in the email alias, so can determine where it came from just from the address.
