Have been using it for a few months now across multiple sites and it is incredibly easy and intuitive to use. I love it so far!

What is there to complain about? It works fantastically.

I have been using Eno for several months and feel secure using it since it gives me a unique credit card number for each website I make a payment and fills in the credit card number, exp and CVV. The only improvement I would like to see is to format the password in such a manner that it is recognizable by LastPass so that LastPass can fill it in instead of me manually entering it, or maybe it is an issue for LastPass to deal with?

I have had nothing but success with this. It picks up the fact that I want to use the credit card, suggests, allows, takes over, and seamlessly completes. Every time I have used it. And remembers the false numbers for future specific site usage. Good job.

Love this extension! A few hicups every now and then, and a lot of features I would love to see added. But it's a great start.

The add-on makes online shopping feel safer by generating virtual numbers and not putting the physical card at risk, works great for me in Chrome and Firefox.

Holy cow, this is amaze-balls! I can't believe I've ever shopped without Eno, it's just so convenient with the auto-filling in and stress-reducing with the virtual numbers. Don't want to give my number to the random website I found? Worried about Target or Amazon getting hacked? I don't have to think about any of that stuff anymore. Just give this a shot and you'll see what I mean!

Works great for me. Helps to have the most up to date version of firefox.

Love Eno! This add-on feels like a friend that helps keep me safe when I'm paying online. :)

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!

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!

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!

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.

I haven't used it yet. But I think it will help me. At least that's what I am hoping.
