One less thing to worry about when it comes to making online purchases. I use it to pay all of my bills too and like how the virtual wallet is set up. Reading the negative reviews, it was only associated with problems opening the extension. I do not know if this will help others, but you go to the upper right hand corner and hit the "Extensions" tab and from there choose to open Eno and it automatically generates a card. This is an extra step as with Chrome it would open automatically when you needed it.
