I love how simple it is to have a virtual card you can use that pops up during the checkout process automatically! I wish all my card companies offered such an option!

I've had zero issues with this since installing this add on. has come in handy multiple times.

This is such a great feature. I love not having to worry so much if a particular merchant isn't doing all they should to keep credit card information safe. This is honestly one of the reasons I have a Capital One card. Keep up the good work.

Can be fritz-y every once in a while, but in general is fantastic. Main complaint at the moment is that in no longer works on mobile Firefox.

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.
