impossible de répondre en retour au mail émetteur en utilisant
replies@relay.firefox.com pour exemple:

nom1.gmail.com ---> nom2(alias).mozmail.com---> nom3.free.fr
ça fonctionne mais

nom3.free.fr --->replies@relay.firefox.com---> nom1.gmail.com

ne fonctionne pas nom1.gmail.com ne reçoit rien en retour

This is a great extension and idea, I've always used 10minutemail and those types of services, but Relay needs some work, you can't choose what address it forwards the emails to. And something very simple, why not add your aliases directly to the window of the extension instead of making you open a whole new tab? So you can save a couple of clicks!
This does serve its purpose though, it is nice and handy.

trop neuf pour donner un avis

How can I SIMPLY report about sites that refused a Relay's alias ?

génial

Ok, my computer is 6 years old, still, 15%+ cpu usage, all the time? Even when I'm just letting firefox run in BG? I haven't used the extension yet, but it hampered everything else.

Great feature! It would be nice to have the possibility to copy the firsts alias directly from the extension's shortcut when forms are not recognized.
