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!

can't figure out how to use it!

I use firefox and i do not want to give them my mobile number. It will not work !!!

Simply does not work.

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.

Capital One tells me they don't have all the accounts activated yet and when they get around to me, they'll let me know. This despite a 823 credit rating and about $15000 a month I put on the card. It's a bad joke

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!

When it comes to Amazon this app does NOTHING... no prompts, no help, just nothing. No idea what is this actually even supposed to do. They tutorial just does some animation of .. I don't even know what. Removing...

I will say off the bat I haven't used it but am sharing why. It seems a great idea to generate virtual numbers to protect your own, but in the fine print it says that they haven't yet been able to limit use of a number to one merchant or transaction, and that each virtual number is live, meaning that a bad employee of a merchant I use could still use that number for a purchase. Ultimately, until a better version comes along, it seems to me that Eno makes it easier for Capital One to track reported fraud, but for the consumer it just multiplies the number of card numbers out there which all point back to my card and make me responsible for payment. Maybe a future version will sort this out! I will stay tuned.
