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.

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.

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

For the non-techy add-on extensions and the many approval and modification to my default settings make question the value of ENO

UPDATE: Just learned that Firefox is not a supported browser for this extension, yet it is available and with 4,758 users, they should probably pull it or communicate that on their addon page... When opening the link: https://www.capitalone.com/applications/eno/virtualnumbers/

I get the following popup:
Browser Not Supported
Eno℠ is currently only available in Google Chrome. Please visit our site from Google Chrome to install Eno℠

* I added the extension to Chrome and all works as it should....
-----------------
I got off to a great start with this add-on also using a Google Voice number (which I use for all of my accounts with no issues), I used it for over a week or two then suddenly it stopped working...

Now when I sign in, all I get is the following 'cute' non informational response! Also the feedback option on it is dead, opens a webpage in a new tab without the ability to provide feedback.

No way to figure out if the service is legitimately down or experiencing issues either.

If it is a GV issue, they should plainly provide that feedback. I am UNABLE to continue using it until the issue is resolved.

If it ever starts working again I will up the stars as it is a brilliant idea, too bad they don't just incorporate VC use/management on their website.

Eno response after trying to sign in:
'Something went wrong

What, exactly? Well, that's what my team is busy figuring out. Please try again later.'

Requires a non-Google Voice number to use for some reason. Even though the number on my account is a GV number. No way around it other than to change the number on my account to one I never use. Idiotic.

They don't tell you how to go to merchants who already have your existing credit card number and change it to a virtual number. Still waiting to find that out.
