Got Premium, and am very disappointed. It doesn't work most of the times, neither the add-on in Firefox, nor getting e-mails on the addresses it generates.

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?

It makes your browser extremely slow. do not use it. turn on only if you need it.

très appréciable

I don't have much has it is my first time, I rated five I believe it will work for my business

More sites are blocking mozmail addresses so this is useless. Addy.io and 10minmail are picking up the slack now.
