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.
