This is worthless. I have never got it to work with Firefox.

Used to love this extension until it stopped working a few months ago.

Now, every time I try to log in, it says "Restart your browser". I have tried fully shutting down and restarting my browser as well as fully restarting my computer, it just doesn't work.

Please fix!!

Verification does not work. Everytime pops up to remind me to use but the problem is the verification does nor work. I don't see an option to enter the CVV to verify at all

doesn't work

My small business card encouraged me to use this extension however it doesn't work with small business cards. It only shows my personal cards. That makes it nearly useless to me since most of my purchases are business purchases.

Seems like a good idea.

Have used it on all the websites where I have subscriptions with no issues. Add on will autodetect a page where CC info is to be entered and launch itself to allow you to link / generate a unique CC number for that site. Websites where it has worked flawlessly: Amazon, Netflix, PayPal, NY Times, CuriosityStream, Comcast. On most of the above, the CC info auto-populated into the correct fields, and on the couple of instances where it did not, the handy "Copy" button allows you to copy / paste the info where needed, or you can enter manually if you choose. The settings cog, which leads to Capital One's VirtualCards website itself also works very well to allow you to see / manage your virtual CC numbers.

Highly recommend this addon.

Works Great!!

Errors out saying something went wrong.... I heard it works just fine on chrome but I will NOT use chrome just for this extension... You need to fix this to work right for Firefox like it did when I first got it.

This addon doesn't work. Not on FIrefox, Not on Chrome, Not on the dark, Not on a train. You try to log in and it just gives a generic error. Waste of time.

They shouldn't force you to use a browser extension for something that you should be able to easily do on the site or app, like making virtual credit card numbers. Maybe I missed another way to do it, but it seemed to force me to this extension. The extension worked ok when I tried it, but required me to go all the way to checkout on the site. If I'm not trusting a site with my credit card info, I definitely don't want to be signed into my capital one account on an extension while visiting that site. Please let us make virtual numbers without this (or apologies if it is possible, I could not figure out how to).

I would love to use the Eno feature, but every time I try, it gets as far as where I am supposed to enter my CCV # and then it quits. There is no place to enter the number, and so it becomes a huge frustration and I just have to give up and use my actual number. A real bummer.

This extension doesn't do anything. It does not allow me to go to the Capital One ENO page. Instead, it just sends me to my Firefox extensions page.
