No reason this shouldn't be working for everybody. This gives me peace of mind that when I send out my credit card number on the site, if their negligence causes retail fraud, I can be certain what site is responsible for that number is linked uniquely to that site. I can easily disable this during periods when I am not buying products. Whenever I need a new prompt for a credit card number, I can easily re-enable it and I'm good to go. While it seems slightly convenient that I would need to sign in again, I am satisfied since it protects my credit card information.

It works absolutely perfect for me. I used to have to go to Chrome to use the ext. I'm glad the ext was finally added to FF. Seems like all the one-star ratings are from people who just can't get over the minimal learning curve. It's actually very simple to use.

Works exactly as described. I don't know why its rated low by others, probably they are using an add on that is blocking it and they don't know how to work the add ons properly. Works just like the Chrome version and I use both interchangeably. Been using it since it was released. Its also survived the major upgrades from Firefox and never ending changes to Win10, never fails. I had over 50 numbers, and recently culled them down to 30s. Thank you for the security provided by VAN. I'd prefer you do something like Citibank, which allows user defined expiration dates on the card and dollar limits on the purchases. There is no need for a collection of CC in the Citi way as it expires faster, making management easier than the long expiration dates of Eno, so I just make new CC # as I need, not tied one to a vendor. I use that a lot too, only Citi has it, AFAIK.

Don't know why anyone has trouble using this. It's simple and it WORKS! I use it, wait a couple of days and delete the virtual number. I haven't had my CC number stolen since I started using it.

For a while this plugin did not work with some of the privacy features I had enabled. On a lark, I thought I'd give it a try again today and to my surprise, it works!

Works great! The auto-fill feature is spotty, works less than half the time, but that's not really a problem, I can copy and paste which is still faster than typing in a credit card number.

Having my credit card number compromised is a huge hassle, can't use my card until I get a new one, and then have to change all my auto-pay settings... anything that helps reduce how often that happens is a good thing! And if this makes it easier for Cap1 to identify the "bad" merchants who let customer data into the wrong hands, all the better.

Have been using it for a few months now across multiple sites and it is incredibly easy and intuitive to use. I love it so far!

What is there to complain about? It works fantastically.

I have been using Eno for several months and feel secure using it since it gives me a unique credit card number for each website I make a payment and fills in the credit card number, exp and CVV. The only improvement I would like to see is to format the password in such a manner that it is recognizable by LastPass so that LastPass can fill it in instead of me manually entering it, or maybe it is an issue for LastPass to deal with?

I have had nothing but success with this. It picks up the fact that I want to use the credit card, suggests, allows, takes over, and seamlessly completes. Every time I have used it. And remembers the false numbers for future specific site usage. Good job.

Love this extension! A few hicups every now and then, and a lot of features I would love to see added. But it's a great start.

The add-on makes online shopping feel safer by generating virtual numbers and not putting the physical card at risk, works great for me in Chrome and Firefox.
