UPDATE I am giving this three stars because I have great hope it but believe it is too expensive for the FireFox spirit. I did have a problem when a logon page appears where I already have an account and FireFox Relay would not let me enter my actual email address to log in. I tried settings in FireFox add-on list and looked online for a support page with a solution; then I had to download an authenticator app on my phone to even make this comment which sparked a developer response that solved my problem! The solution, though, removes the helpful icon from every page where I might want to use it to create the temporary screen email. While I was looking at the solution (which was at a location not intuitive to me), I found another default setting to change.

Very nice, but wish add-on showed emails. If a website doesnt have the autofill with relay, its irritating to click multiple buttons to get to my emails, instead of the add-on in the tab bar just showing my emails

是否可以删除右键菜单？
Can I delete right click menu?

Deleted it before I could really use it because it made the email box where the little purple star was in at the right "sticky" on top. IE, when a popup from the website popped up, the email box was on top of the popup, blocking a large part of the text and I couldn't read it. Maddening.

Half baked, with a shaky future. Lockwise, Sync, Monitor, DNS over https, VPN all will fade away if you won't pay for a subscription. Other email obfuscation service plugins are still easier, unlimited.

please let us customize the email

It is to soon to be writing a review. That is why I changed my rating.

Sometimes painful because it blocks the possibility of entering an address other than that generated by Firefox Alias. Last example for me: the "Laposte.fr" site.
So, you have to go to the plugins page to deactivate the extension, then come back later to reactivate it. Why not provide temporary deactivation by clicking on the icon?

Cool idea - not new but convenient. Price is worth trying premium. Two concerns:

1) Custom email domains are susceptible to email spamming since you simply create a new address as you like. I would give up a little flexibility to ensure no one could simply create an alias email address on the fly. This would mean creating the alias first in the extension or interface, assigning a real email address and then use the alias on a site. This way spammers or bots couldn't just make a whole bunch of aliases connected to your domain. While I can appreciate the flexibility to create a new alias quickly this comes at a cost and is subject to abuse.

2) How can I manage my aliases using a mobile device? I haven't figured this out yet if it is indeed possible.

I am trying to verify my email on a site i signed up for and it said it sent it for me to verify but Yahoo does not have the verification. Not even in the spam folder. So i cant try out the free trial correctly before deciding to purchase the subscription. FF sent me here to report that it didn't work but this rating is the only thing i see to contact Mozilla to report it. Great concept that I would consider using after my 5 trial uses...if i could figure out how it worked.

A lot of sites won't accept @foo.mozmail.com. They flag the second "." as being invalid. It would be nice if the separator between my domain and "mozmail.com" could be a "-"

je decouvre a l'instant,plus qu'a la tester en somme....
