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

Just getting started

Just hangs in Firefox. Great idea, poor execution. Just use privacy.com

Completely broken.

This app is totally disconnected to Capital One. I tried to access my virtual card as I had a need to use it, and it is a new Quick Silver credit card. It declined me access. Accordingly it will only work with Venture, QS and business cards. What do you of the card that I just had? Dumb app.

If you use Firefox don't waste your time

Does not work with Firefox. Says it will check the session, goes through a log in loop repeatedly but never logs in.

Works in Firefox if you downgrade to version 94.0.2

Same exasperating problems as others have had with this app. With so many complaints, does anyone at Capital One even bother to read the reviews, much less consider doing something about the issues?

Doesn't work with Firefox. Endless login loop.

It's broken as others have said. When I click sign in the sign in window closes instantly

This addon is a good idea, but it does not consistently work...

The current iteration of the app it is impossible to login.

You click the window to login, then the window opens to login, then that window immediately closes and the little drop down refreshes... and it still shows the button to login...

And this isn't the only bug, I've had similar bugs in the past, but then they fix them, Sometimes these bugs are fixed by turning privacy features off, but I've gone through the I can't login... oh I can!... I can't login... I can login, but autofill doesn't work. loop several times now.

It's very frustrating.

The service itself (time-limited credit card numbers) is a good idea, but this addon is terrible. Capital One Does not seem to want to allow the app to work in the presence of other apps or with non-default configurations for privacty settings... and that's not OK.

This started failing a few months ago. Not sure if was from an update of Firefox or bad cookie. The pop-up to sign-in with browser launches a window comes up with another small window pops up and they both disappear. It is throwing an exception. I tried uninstalling and reinstalling and the same happens and couldn't complete the setup process. I did however discover a workaround to this. Go to a new Firefox browser window and sign into your Capital One account Then go back to the window you want to use a virtual account number for, select the Eno extension and it properly works. After I did this once, after logging out of Capital One. I tried again selecting the Eno externs and the sign-in with browser launches a pop-up window and allows me to sign-in

this is not working on firefox. the popup window closes automatically upon opening

Most times I try to use it, it says "Securely signing you in with express checkout..." and never gets any further.

Same experience as others. When I clicked on the Eno icon from my Firefox toolbar, the CapitalOne login window will open very briefly and then close. Eno only works if you first log into your CapitalOne account in another tab.

Stopped working a couple of months ago. Pops up saying "Checking Session" and then says you need to log in. After clicking to "Log in with browser" a window opens, then shrinks, and disappears. DOES NOT WORK

Exasperating!! just got an error message saying "Your ebay purchase was declined because you used a virtual card number you created for ebay... Use a virtual card number created for ebay to retry this purchase." ABSURD!!! it fails more often than it works, I give up. I'm taking it off my extensions.

No longer working after update. It always tells me to sign on by browser. However the pop up opens then shrinks and disappears each time.

As many other users mentioned, this stopped working the last time Capital One put out a new version about a month ago.
For me, when I click on the Eno logo and "Checking Session" appears, if I need to sign in a new window pops up for the login but then immediately shrinks and closes with out giving me the opportunity to put in my credentials. I was able to make it work again for 2 uses by uninstalling and reinstalling the add-on. Also, the work arounds others mention, go sign into C.Ones website, then open a new tab (or three) on the same retailer allow me to struggle through.
Honestly, I may drop Capital One if this isn't fixed, there are competitors with apps that work.

PLEASE MAKE IT WORK WITH FIREFOX!
