It doesn't work, I try to login in but then it opens up a pop up window and it closes immediately. I tried many times, un-installing and installing it, same issue. Works in Chrome though.

A window opens briefly then disappears, Worthless. Could not get it to work.

Auto-closes sign-in window before I can interact with it.

It doesn't work, I try to login in but then it opens up a pop up window and it closes that one ask me to log in again, tried at least 10 times, same issue

doesn't work at all

Simply does not work. Chrome version works fine on Vivaldi.

Broken for years now. Such a shame.

Does not work with FireFox at all. Using virtual cards from Citi instead.

Set it and forget it? Ha! It used to work, now it is on an endless loop trying to log in and just locks the computer.

It no longer works with Mozilla Firefox. It just keeps spinning and says "Checking Session". Please fix this.

As others have mentioned, this add-on hasn't worked in months even with the most recent update (2/28/2022). I really like the concept so this is a HUGE disappointment. Maybe if enough of us drop Capitol Once they'll take it more seriously and actually fix it.

Doesn't work in Firefox. Just spins. Used to work. Hasn't for the last month+. :(

This review is for version 3.6.2 in Firefox.

I love the idea of virtual cards and it's a great way to manage/control online credit card use. However, as LOTS of others have noted, it used to work fine in Firefox but broke months ago.

I've called Capital One multiple times to complain. When I talked with them today they claimed it's a "known issue" and they recommend using Chrome.

I urge others to not just leave reviews, but clog up their phone support with complaints. Once they spend more on phone support than it will cost to fix it, that may get some action.

As a workaround, most, but not all of the time, if I open a tab and login to my Capital One account before opening another tab for the website where I am shopping and trying to use Eno, it will work. However, today it just hung, so I lost my shopping cart.

Doesn't Work. I have to go to the Capital One website every time.

I used to use it on Firefox and liked it a lot (5 stars). However, for the past few months it has not appeared when I'm checking out, and I have been unable to call it up or use it. I've changed nothing, except that I'm using Firefox v96.0.2 now. I'm very disappointed.

hasn't worked in weeks. sign in window appears and disappears
