Doesn't work: "Something went wrong" in both the add-on popup, and their setup page (capitalone.com/applications/eno/virtualnumbers/setup). Tried 5 times to sign in, with my username/password copied from the clipboard to make sure I didn't mistype anything. Also tried the Chrome extension - same failure.

GIVE ME A USEFUL ERROR! Not "Something went wrong". This is Error Management 101.

An it's not a "third party cookies problem". I made sure Firefox didn't block anything, and setup didn't work from CapitalOne's own setup page (no 3rd party situation there). This add-on is just broken.

Also, add-ons like these, that require permissions to READ AND CHANGE ALL THE DATA ON WEBSITES YOU VISIT, are a security nightmare. I worked at Google, and I can tell you there are easy ways to make extensions *request permissions on demand*, in a site-specific manner, instead of asking for that blank permission upfront, which most hapless users will automatically grant.

If this extension gets compromised (as quite a few others have), you're screwed. It will be able to read your bank/credit card/online Bitcoin wallet/ANY OTHER PASSWORD and data.

And it doesn't even work.

Uninstalled.

If you're looking for a simple and reliable alternative, sign up for Privacy.com. No spying extension to install - just generate card numbers from their website.

Advice for Capital One: you may think you're making it more convenient for customers to provide an add-on instead of a simple page to generate virtual CC #s from your own website (like Privacy.com does). Well, you're not. The more complicated a solution is, the higher the likelihood for it to fail.

If you really want to offer virtual card numbers for your customers, please do so in a simple, honest, transparent way - like Privacy.com. You have the advantage of the brand, cashback etc.

Works as it should. Love it

Doesn't work....
installed and logged in but says both of my personal cards don't qualify. :(

I really love this app when it works, but it doesn't work a lot. It frequently hangs when trying to load my information.

EDIT: Version 4.0.0 doesn't work

Quick easy setup. Used it once so far. simple to use

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.

This thing is WORTHLESS!! Here's what I see: " Your virtual numbers got a makeover.
They'll now look something like this:" with a picture of Nicole's Nectarines and NO way for me to actually USE the thing!! No links, no place to fill anything in, or number to copy. "New look, same benefits" Yeah? Guess so, same 0 benefits.

Sounded like a good idea. But, it wouldn't load. The "just a moment" stretched to over 5 minutes. I may try again when I have an afternoon free.

Every time I close my browser I am logged out. When I log back in, I have to go through the entire process of setting this up all over again from scratch. So this works, but barely.

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.

Used to be 5 stars, but as other reviewers have stated--Eno stopped working a few months ago (I now get stuck in a sign-in loop whenever the add-on is invoked), and dev hasn't responded with anything helpful. Clearing cookies/cache/history does NOTHING. Highly disappointing!
