This app is janky, and considering how much $$$ CapitalOne has at it's disposal, there no good excuse. It freezes up with every use. You need to keep signing into your Capital One account. And it doesn't auto-populate the newly created card into the online shop. You need to copy and paste it all manually from the CapitalOne website. It has not been updated for A WHOLE YEAR, so who knows if it's secure.

Never loads when you need it to. Just sits there saying it's trying to log in or trying to create a card. All I want to do is check out quickly, but I have to close firefox and reload everything in Chrome instead.

Didn't work - can't make it past the mobile number verification step to log in.

Used to be great, now it rarely works.

This app is total crap. Will not log in on any platform. Acts like malware.

When it works, I give it a 5/5. The problem is it works MAYBE 2% of the time. The other 98% I have to try refreshing the page, signing in 500 times, uninstalling and reinstalling, signing in another 500 times, it's such a hassle to use I just log into my account and manage it that way instead of using the extension because it never works!!!

Can't pass mobile number verification step. Always get "Something Wrong" error. I have a valid mobile number used everywhere.

I am so sick and tired of the pain of using this app. Every time I log on it's like I've never used it all these years. I have to "add" the extension but first verify AGAIN it's me then add the extension then login AGAIN. Most times I have to enter capitol one and login then open eno virtual cards to get it to work. All and all you could probably pay me the $Millions you're paying your "developers" and "maintainers" and get a better product. So sick of ZERO customer service.

I've tested this sporadically over the years, and I've never been able to log in. I've disabled ad-block and site security. I've even tried the Chrome version, and I cannot ever log in.

I was never able to successfully login with this extension. Waste of time.

This add-on does not function with Firefox. It won't start up after Firefox update. Firefox version 129.0 (64-bit) for Linux Mint 23.3 Cinnamon Linux Kernel 5.15.0-119-generic

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.
