No work no function no bueno. Awesome idea but no carry-through.

Quite amazing that this plug in still suffers from the problems of not staying signed in, or being able to sign in at all. Very sad.

Does not even allow to sign-in on Firefox.

This extension worked great when I first added it. Like everyone else lately, I find it no longer works, especially since the last firefox update that removed the extension buttons at the top where you could click on the extension you wanted to use. I contacted Capital One to complain and suggest they need to allow people the ability to create new virtual cards from within the app or on the website. I was told they are working on all these things. And that Eno is a third party thing separate from Captial One which I don't see where you can contact them from. Only suggestion was to use Google Chrome instead which I chose not to use anymore several years ago. Hope this info is helpful to someone out there!

Easily the worst extension that I'm forced to use. The multiple virtual card functionality isn't available through the website, and this extension barely works on a good day. It logs me out all the time, and frequently won't let me log back in.

I'd rate it if it worked. It keeps complaining about a difficulty.

Trash. Does not work properly on Mozilla half the time.

I am using eno in Firefox on a mac. It frequently fails. I have the same experience that others have posted here. I try to log in, it brings up another window, the window goes away without logging me in, and I'm back at the original window. I have contacted Firefox and they say to contact Capital One. I have contacted Capital One and they say it works.

Doesn't seem to work. A window seems to pop up for about half a second and then disappears. Never gets to the act of creating a virtual number.

Works whenever it feels like it. Usually not when you REALLY need it. CapitalOne, do better.

Well, tech phone support was useless. I was able to use this, and then never again. It's probably because I use Multi-Account Containers: https://youtu.be/TadM5fqx6uY

Works great...when it works. This extension is super buggy and unreliable. I'd say works about 10% of the time and the rest it gets hung in endless login loops, loading screens, etc. Please do better Capital One.

3/4 of the time, the app fails to login and I have to go through the longer process of logging into Capital One, verifying myself, create a new virtual card, etc. I call Capital One once a month to continue notifying them of the failings of this app.

When this extension works, it's excellent. That's less than 50% of the time unfortunately which is extremely frustrating.

The most common problem is arriving at the payment page of a merchant, activating Eno, which brings up a sign-in pop up. Pushing the sign-in makes the actual logon screen flicker and disappear. Eno puts you in an infinite retry loop, which makes payment impossible.

This problem has existed for more than a year, which is solidifying Capital One's reputation for being unresponsive to the needs of customers who are trying unsuccessfully to use Capital One as a payment provider.

RELATED REQuEST
Please put virtual card creation capability on your mobile app. My mobile online payments are significant and unfortunately Capital One isn't a player because of lack of virtual card creation on my mobile phone.

Unlike the extension for Chrome, this addon does not allow me to sign in. The entire system seems to be different, and I can't figure out how to use it, while on Chrome I had no problems at all.

Doesn't work. Just useless.

It's great when it works, but it's so unreliable! Not working at all now.

As many others have said, the popup used to log into Capital One Eno closes immediately therefore there is no way to log in and use it.

Capital One, fix this please ASAP.
