First time I used it, I loved it. I was able to set up multiple websites, easy as pie. After the first couple times however, I couldn't get logged in. It didn't recognize me, asked me to sign up, and asked me to verify by text message. After verifying, it asked again. It asked approximately 10 or so times in a row before it told me that I reached a limit for text messages. Sometime during that, it asked for my card security code twice, and I got an email twice thanking me for signing up, after I had already signed up!

Somehow it started working again, and has worked since. Weird, but still needs polishing

so far it doesn't give me a code, so doesn't work

Love this app, sets up a unique credit card number for each online account, so if that company is hacked they don't have my actual credit card number. Brilliant!

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.

Hard to get around. Not user friendly.

Can you please specify which 3rd party cookies sites must be added to the exceptions list? It is irritating to have a blanket accept policy for third party cookies for the Eno extension to work.

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!
