I signed up for FireFox Relay but nothing changed. No email aliases were used or bounced back for that matter. Very mysterious this is!
Firefox User.

Ironically, with this add-on you are able to hide your email from "hackers" but you have to give the add-on all your data from every website you visit.

Relay is BLOCKING some of my website logins. WHY!!!???

The update makes some website (Linkedin) fonts so big.

Latest update breaks site font size

These accounts seem to be banned by jrebel.com,

Sometimes this works, but not all the time. I have an outlook.com email address, and the email "bounced", so it didn't send. However, because it did this, it has temporarily suspended the email forwarding for more than a day! ALL of my aliases are blocked simply because ONE email did not send correctly! This is very frustrating, and it might be understandable (barely if at all) if the wait was like 10 minutes, but waiting more than a day is too much (32 hours). There also should be an option to view these emails that have "bounced", on the dashboard, or at least a "retry" button to attempt to send it again.

This service is useful and cool when it works, but it's just frustrating when it doesn't. Developers, please fix both the email "bouncing" problem AND shorten (or remove) the time that the service is disabled.

A nice idea, but you should explain that it's not completely free right at the beggining. It feels like you're mocking me when after reading everything I enter and realise I have 5 free tries and no more...

J'utilise Firefox relay depuis une semaine mais je ne reçois pas les messages sur les alias. Pas très pratique en cas de commande sur internet...Donc soit je n'ai pas compris comment ça marche soit ça ne marche pas.

I agree with him 100%:

"Would be a nice extension but adding a commercial plug to my context menu is a total no-go and a reason to delete that extension at once!"

very bad, for my outlook.com address I received: We are currently unable to deliver emails to xxx@outlook.com. We received a soft "bounce message" from your email provider when we tried to forward the email to you. This can happen if Relay couldn't connect to your email provider or if your inbox is full. We'll try again on 01/17/2022 07:49.

My inbox is not full!

I really want to like this add-on but the first test message I tried, forwarded to my Yahoo mail account resulted in a message:
"We couldn't load this message retry". Retry yielded the same result.

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

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.
