I've had zero issues with this since installing this add on. has come in handy multiple times.

This is such a great feature. I love not having to worry so much if a particular merchant isn't doing all they should to keep credit card information safe. This is honestly one of the reasons I have a Capital One card. Keep up the good work.

This thing is WORTHLESS!! Here's what I see: " Your virtual numbers got a makeover.
They'll now look something like this:" with a picture of Nicole's Nectarines and NO way for me to actually USE the thing!! No links, no place to fill anything in, or number to copy. "New look, same benefits" Yeah? Guess so, same 0 benefits.

Sounded like a good idea. But, it wouldn't load. The "just a moment" stretched to over 5 minutes. I may try again when I have an afternoon free.

Every time I close my browser I am logged out. When I log back in, I have to go through the entire process of setting this up all over again from scratch. So this works, but barely.

Can be fritz-y every once in a while, but in general is fantastic. Main complaint at the moment is that in no longer works on mobile Firefox.

Used to be 5 stars, but as other reviewers have stated--Eno stopped working a few months ago (I now get stuck in a sign-in loop whenever the add-on is invoked), and dev hasn't responded with anything helpful. Clearing cookies/cache/history does NOTHING. Highly disappointing!

First time I used it, I loved it. I was able to set up multiple websites, easy as pie. After the first couple times however, I couldn't get logged in. It didn't recognize me, asked me to sign up, and asked me to verify by text message. After verifying, it asked again. It asked approximately 10 or so times in a row before it told me that I reached a limit for text messages. Sometime during that, it asked for my card security code twice, and I got an email twice thanking me for signing up, after I had already signed up!

Somehow it started working again, and has worked since. Weird, but still needs polishing

so far it doesn't give me a code, so doesn't work

Love this app, sets up a unique credit card number for each online account, so if that company is hacked they don't have my actual credit card number. Brilliant!

No reason this shouldn't be working for everybody. This gives me peace of mind that when I send out my credit card number on the site, if their negligence causes retail fraud, I can be certain what site is responsible for that number is linked uniquely to that site. I can easily disable this during periods when I am not buying products. Whenever I need a new prompt for a credit card number, I can easily re-enable it and I'm good to go. While it seems slightly convenient that I would need to sign in again, I am satisfied since it protects my credit card information.
