Great but missing features and lacks some finessing:

1. cannot manage aliases from the plugin (like stop forwarding), have to login to mozilla to do that.

2. creating a random alias scrolls down for some reason?

I don't like how "Allow Mozilla to collect interaction data" is automatically on, other than that, really, really useful and good!

i only want dark mode in exteeension

now i have 5 alternative emails to use for free storage on mega.nz!!

It would be nice if there was an option to remove Relay from the right click menu entirely. The extensions button in the toolbar is easy enough way to access the needed functionality.

Doesn't work on some sites but it is a great security and anonymity feature

Only 5 free emails instead of unlimited, no main mask email and its slower, all that in distinction with duckduckgo, but it is integrated with multi account containers, so I am using duckduckgo for main email and that for others.
