Eno makes it really easy to shop online without putting my real credit card number out there for hackers to potentially steal. The setup process was quick and painless, and now Eno pops up to help me out whenever I'm getting ready to buy something!

Eno is my favorite online shopping companion! It's so nice to have unique payment info at my fingertips, and I love being able to lock and unlock numbers. I'll never share my real 16 digits online again!

Firefox add-on doesn't work. Every time I try to use it, I get the error message "Something went wrong.
What, exactly? Well, that's what my team is busy figuring out. Please try again later." I've tried every day for the past week and no luck. Firefox is up to date, so I don't know what the problem is. Disappointing.

Developers: can you please help? The Eno page on the Capital One website has disappeared so I don't know how to reach out to you.

I have been using Eno and love it! Keeps my real card safe and is easy to use! Capital One is the only way to go!

1. Keeps telling me to update my browser when it is up to date.
2. Why I need an add on and can't generate one on the main site is beyond me.

Update 8/20/2019 - The last several times I've tried to use Eno, I get the " 'Something went wrong' What, exactly? Well, that's what my team is busy figuring out. Please try again later." I'm removing the app until it starts working again! Took it from 5 stars down to 1.

Update 5/4/2019 - Apparently Eno is no longer supported by Firefox. "Eno from Capital One could not be verified for use in Firefox and has been disabled."

This is a terrific add-on! Added to Firefox toolbar. Works seamlessly. Click on the Eno icon in the toolbar to create a virtual card, select a virtual card you've already used on a website, or manage your virtual cards. Secure way to shop without compromising your actual card number. BTW, this also works for Chrome equally well.

WARNING
This system only works in the USA, it does not work in the UK !
customer service in the UK has no information at all, wasted my time setting up a UK card to be able to use ENO and now find its not for UK. THEY SHOULD WARN PEOPLE

It can't match my phone account with my Capitol One account which is crazy since I can do all my banking with Capitol One on that phone. It was a useful add-on until it got stupid regarding the phone number. I set up 3 cards and I can check on them, still use them, but I can't create new ones because Eno is brain dead about my phone. Back to BoA because it still works.

It doesn't work with Firefox and Windows 7.

Completely broken, hasn't worked once over months and months. Abandoneware at it's finest from a bank no less.

I does not work. it works perfect in Chrome

now only supports Chrome, man that just sucks

If your mobile phone is a pay as you go like Trac Fone, the app doesn't recognize the mobile phone as yours, so the app doesn't completely load so you can't use Eno.

Does not always detect payment fields.

I went into all the websites that had my real credit card information and have updated them to use virtual numbers. Love using this for all my online purchases, never have to get up and get my wallet again!

Firefox add-on doesn't work, except on Capital One page. Can log into Cap1 and generate numbers, but too much annoyance.

Does not work. I got a "something went wrong" error message.

Would love to use this on my credit card for online purchases but it simply DOES NOT WORK. I've tried repeatedly to set it up and always just get "Something went wrong." with no way to receive support.

Update: Original review mentioned that the add-on popup button doesn't appear in my toolbar. While this is true, Eno is still running in the background and will appear if it detects credit card form elements.

It would be great to see the popup icon all the time for access to general functions like managing virtual cards, but Eno is perfectly functional without it.

Installed and it doesnt even work it just says "our team is figuring out whats wrong"
