Pretty handy. It's a little finicky, maybe because I'm on Linux, and gets "stuck" once in a while. Sometimes I have to go log in to CapOne in another window before the extension will work. But very handy for keeping CC numbers separated and limiting the blast radius of an exposure. I especially like the ability to turn virtual cards off when not in use or at a future date - E.G. when signing up for a free trial service I do not intend to renew.

I've installed ENO numerous times on Firefox and it keeps disappearing.

Works great. Easy to add a new virtual card and use it. Locks down fraud to just that virtual card if there is any.

I feel so much safer with my financial transactions using Eno, because I am.

It makes transactions safer. I wish that more sellers would accommodate this feature.

This system is brilliant! The extension is sometimes a little wonky, but the concept of virtual cards is genius!

You would have to be crazy not to use this. All credit card company's should do this to make the made up number exclusive to the sites you purchase on and cannot be used anywhere else

It works properly now.

This is a great idea, but doesn't always work. Sometimes the extention, Eno, doesn't load.

Other than the occasional 'getting stuck' when the app opens at checkout, I think this product is great! Being able to quickly lock/unlock a virtual card number? Fabulous! Creating a virtual card number when required to input a credit card number just for a "trial period" and then locking the number so you don't get stuck with recurring charges? An Absolute God-Send!! Thank You, Capital One!!!

Worked really well using Firefox!

Virtual card refused because linked to canceled card. Doesn't let me request a new viertual card. Sucks!

When it works, it is great. But it hardly ever works for me. I can't even login to get it working now which is unfortunate. It has been like this for months. I have disabled all ad blocks and anti-tracking options and it still doesn't work. Simply closes the pop up right away.

The virtual card works fine with Chrome but doesn't with Firefox.

Update: Amonth later and I just had to un-install/re-install the extention again!
Totally frozen in toolbar this time. Obviously the "bug" wasn't fixed!

Orig: This extension is getting worse by the day. For the last year it rarely worked on weekends and for the last few months it worked maybe 50% of the time. It hasn't worked now for the last 4 days. I uninstalled and reinstalled the extension today and it froze on the website and wouldn't close. I had to clost the website and reopen it to make a payment. Needless to say I used Paypal which has never ever failed. Very unhappy with FF. Everyone is pushing Chrome. I've been with FF from it's inception but I am running out of patience.
