Does not work. Added to Firefox and the settings say it's active but I can't find it anywhere to use it. ZERO stars.

I've installed ENO numerous times on Firefox and it keeps disappearing.

When it works, it is great. But it hardly ever works for me. I can't even login to get it working now which is unfortunate. It has been like this for months. I have disabled all ad blocks and anti-tracking options and it still doesn't work. Simply closes the pop up right away.

The virtual card works fine with Chrome but doesn't with Firefox.

Update: Amonth later and I just had to un-install/re-install the extention again!
Totally frozen in toolbar this time. Obviously the "bug" wasn't fixed!

Orig: This extension is getting worse by the day. For the last year it rarely worked on weekends and for the last few months it worked maybe 50% of the time. It hasn't worked now for the last 4 days. I uninstalled and reinstalled the extension today and it froze on the website and wouldn't close. I had to clost the website and reopen it to make a payment. Needless to say I used Paypal which has never ever failed. Very unhappy with FF. Everyone is pushing Chrome. I've been with FF from it's inception but I am running out of patience.

It doesn't work.

This extension is extremely buggy.
If it gets stuck in a login/error loop, you can open a new tab and log into the captial one website. then re-open this extension and it'll work.
Aside for the login/something went wrong error, it absolutely kills memory usage. Specifically when visiting a site like lowes.com. It maxed out my memory usage and started to freeze firefox. Initially I thought the latest firefox update was the problem. Nope, as soon as I disabled this extension I saw my memory usage drop like a stone.

Just doesn't work - tries to login and either the login screen disappears or get a message saying "Something went wrong"

Doesn't work, calling tech support didn't help.

One star because it creates a memory leak with youtube livestreams when chat is open scanning every message for autofill fields.

worthless piece of s#$t !!!!!

This extension has always worked poorly and now only lets certain types of card holders use it at all, with no notice of the change. Bad extension, bad support, shame on Capitalone

This generally doesn't work. Any time it pops up to log in, the page flashes in a popup window, immediately closes, and fails. I haven't found any workarounds that work - other than switching to Chrome whenever I need to use it. The most frustrating aspect of this is the browser extension is the _only_ way to generate virtual card numbers, for absolutely no reason at all. If I could just go to the Capital One website to do it instead then I wouldn't even be all that bothered that this extension never works.

It used to work, though it was always hard to login. I figured out it was best to login using your browser in a tab first before trying to login to Eno. More recently it's basically unusable. I can login with my trickery most of the time but I can't get cards to load.

Really cool idea and original implementation, but Capital One has shown it cannot keep software working. I bet they cut the development team after they delivered; classic BigCorp nonsense that destroys products.

troublesome extension. great when it loads but typically it crashes!!!!!

Tried to verify my identity and said my phone number didn't belong to me. I've had this phone number for about 10 years now.

Unable to log-in. This plugin works great in Chrome but is useless in Firefox.

No work no function no bueno. Awesome idea but no carry-through.

Quite amazing that this plug in still suffers from the problems of not staying signed in, or being able to sign in at all. Very sad.
