This is such a useful feature to have for my Capital One cards. It gives me peace of mind when I shopping online. I have dealt with fraudulent transactions on a different credit card and it's such a headache. With Eno I don't have to worry as much because if someone get the card number I can just delete the virtual number without replacing my entire card and the headache of changing every auto payment. It has worked for me every time I have used it. I could see where the pop up might be bothersome if Capital One isn't your primary card but I don't mind just closing when it's not needed.

Good concept but very poorly implemented and ultimately not usable. You can only use the add-on the very first time you install it. So I have to basically clear the browser cache and reinstall the whole thing again to manage the numbers. It just keeps saying "sign in with your browser" but after a million times of signing into the new window, it won't actually sign in. I have 2FA enabled.

To add insult to injury, these people did not build a way to simply manage your virtual cards in the capital one website interface. That's a level of hubris I have not seen from any developer worth their salt - to not create a fallback option in the web interface. Why not just let people create/manage virtual catds on CapOne online interface in case your plugin doesn't work (which based on the reviews, is clearly the case).

I HATE that the default install is to have a pop-up every time I checkout somewhere on line. Did you ever think that maybe I have more than one credit card and don't use Capital One EVERY TIME?!?!?

Please tell me how to TURN OFF THE POP UP!!!!!

Love it. Gives me such peace of mind when I am purchasing things online.

Great feature but the extension is poorly written. It will use a considerable amount of thread time in firefox causing the entire browser to lag.

Helps shopping become even simplier!

Normally Eno works very well for me. It's a great tool! It somewhat frequently gets stuck on a loading screen when I use it and I have to refresh the page. Kind of annoying, but not a huge issue.

It doesn't like my phone number, the phone number I used an entire hour ago to verify my brand new capital one account.
Support couldn't help, their suggestion boiled down to "try again later".
I really wish I could just use a website instead of a shitty broken addon.

EDIT:
I am not on those platforms.
I was on the phone with your website support yesterday, if you think you can do better than your existing website support, please provide a reasonable support channel like an email address.

I have to restart via the website EVERY time I try to use this extension!! Anyone have a method to keep this from happening??

Does not work! Only says "Checking Session" indefinitely. Before the last update I had to re-register my card every time I wanted to use it. A real pain in the _ss to use.

as an update to my review, my experience has now crossed over into pure hatred for this piece of junk, and my opinion of Capital One has gone down because of it. How hard can it possibly be to just allow a not stupid login system like browsers have had for generations

It's a great security feature, but is a little hit-or-miss whether it logs in or not, and it makes me sad I can't just use it in my Banking container to generate numbers, since that defeats the purpose of having containers in Firefox

Used to work. Now continuous "checking Session". Ubuntu Linux 21.10 Firefox 86.0. I wouldn't be caught dead on social media. If you need more information, jgd (at) neon-john.com.

I have always had "delete cookies on exit" set and will continue to do so and use the "manage cookies" feature to save vital cookies. You need to specify the third party cookie site that should be in the exceptions file. There is now "enable third party cookies" setting in this version of firefox.

suggestion: Instead of trying to figure out a CC input form, simply provide the user a button to create a new number for the current checkout page.

to hard to install

Used to work great, but now won't open. Capital One support has no information about Eno.

I see a lot of people having problems, but so far it's been working like a champ for me, even on my Mac. Super quick and easy compared to what I had been using with another card company.

Works great! If your card gets stolen from a website, it's isolated to that website, so it reduces the issue.
