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.

It doesn't work.

It's very useful when it works. However it doesn't work 40% of the time. Sometimes it opens right when you need it, sometimes it won't open when you click it, and sometimes it just hangs at a loading screen. Very frustrating

Doesn't always open in Firefox to create new virtual card.

Increases CPU usage on some sites when moving the page, and has issues with login flows. Other than that, works well.

This add-on just keeps getting better! It understands web pages faster and makes the whole process seamless and did I say FAST?!! Thanks for the great peace of mind, ENO!

While I like it when it works, it doesn't work half the time. It's had the exact same issues for years. Sometimes it will just sit there like it's signing in, only it never does. Other times it will ask you to login, and then the login box pops up and immediately disappears. I've witnessed these same issues on more than one computer/browser.
