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.

DOES NOT WORK. POS!

Great when it works, but will periodically say it needs me to restart browser to update itself, but there is no update and it doesn't work even after restarting. And when I close Firefox, I automatically delete all site data, so the problem is not cookies or something like that.

It's great when it works. The problem is it almost never works.

Login looping since the last update on july 19th

Heads up: eno does NOT work on the latest firefox version 103 (updated sometime towards the end of July. I rolled back my firefox to version 102 and the eno works perfectly. I do not know who is responsible for fixing this - eno (capital one) or firefox dev.

Same problem as everyone else. Sign in window opens and closes. I have been able to sign in but the Eno window doesn't create a virtual card. I just called Capital One and their tech guy said to use Chrome or I should wait a few hours and see if it works then. What a low quality tech guy, but I am not surprised. I am thinking that Firefox has done something to cause this. It seems if they offer an extension, they should check to see it will work on their browser, kind of a no-brainer. I have updated on a regular basis when available. So can the Firefox tech guys please look into this.

Worked OK until recently. Now "Sign in with your browser" opens one window, then another small one, then both automatically close and nothing happens. I've tried setting the browser to the most permissive policies ( regarding popup windows etc) and it still doesn't work

Have used this for sometime and it has worked great, until recently. Same issue with Open in Browser window flashing open then closing. It is really handy when it works.

doesn't log in

Stopped working, useless, frustrating. as of firefox 103 this is a dangerous paperweight attached to your credit limit. You log in, it opens the window, you login, and it disappears, opens a MICROSCOPIC window in the corner which immediately disappears (terrifying), and you're left staring at what you're sure was just a successful phishing attempt.

Disgusting that such a large company can't manage to stay on top of the second largest browser's updates.

No longer works with firefox 103 update

Just installed ... flashes and cant sign in.... how did this product get released?
