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

FIX FOR ENO NOT WORKING:

The Problem - The probable reason for Eno extension not working is that you need to log in. Eno pops up a window to log into your CapitalOne account. The popup window closes rapidly and apparently fails to log you in so Eno simply doesn't work.

The Solution - The solution for me has been to add an exception to your browser's security policy. Settings -> Privacy & Security. Then scroll down to Cookies and Site Data. Click Manage Exceptions and add an exception for "https://verified.capitalone.com". Now try clicking the Eno login button again. If it still doesn't work, refresh the page.

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.

Great idea that worked unreliably for years. Suddenly I can't use it at all. CapOne tells me I have to start using the app in order to validate. I am not putting their invasive app on my phone. So now I have dozens of virtual cards that I can't access.

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.

It's nice when it works. Probably logs me in a little less than half of the time. Why isn't all this functionality in the main mobile app anyway??

The same as other reviewers, I could not make this work in Firefox. The popup would appear and then disappear instantly. But then I installed it on Chrome, and it worked well there. So, I split the difference between one star and five stars.

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.
