not working on all web sites

It used to work fine, but now it's terrible, it makes you sign on over and over again and it takes you nowhere. I would give it a zero stars if I could. ( I also don't know why this post is dated a year ago, when I'm writing it today and is February 6th. 2022)

The setup wouldn't even let me get pass the login screen

Eno could be so much better, like the Citibank version. It should let you set a credit limit and an expiration date to give you much better security functions. With long expiration dates, the potential for abuse is much greater.

Update Jan. 2026:
The extension works so infrequently that I can't believe this is a product they still want users to install. Whatever is going on at Capital One, they've abandoned making this product stable and reliable, which is a real disappointment. I used to really enjoy using the virtual CCs for online transactions, but at this point I'm having to go to the CapOne website to manage and retrieve them.

This extension has been adding more and more RUM telemetry components, which access more and more random URLs behind the scenes, and the actual functionality of the app has been declining constantly. Every time I try to use the extension lately, I get the "Checking Session" message and it just constantly spins. And accessing the virtual card list from the website is such a pain that at this point they're useless.

For the past month or so, Eno will not generate the virtual card numbers I already have, forcing me to reenter my credit card numbers time and again.

Fails to log in 95% of the time. Capital one website shows virtual cards, but doesn't allow creation of them without this god-awful add-on. Great idea, horrific execution.

Spent the 30 minutes to do the 15 convoluted steps to set this all up, and of course it doesn't work. BofA had a much nicer setup, that didn't need a lame plugin. I would not be suprised if they are sniffing all your web browsing with this either. zero stars

The number did not work when I tried it. I deleted the number thinking I could recreate it. NOT.

This used to work fine for me and as many reviews have said, now it is just an endless authentication loop.

It used to work, now it doesn't. Tired of searching for solutions, so now I switch to Chrome to pay for items, followed by an immediate virus scan that always shows multiple PUPs. Tedious, but it is important to protect my credit card information.

I LOVED this add on until it stopped working. I used it exclusively and then it just stopped working on my Firefox browser. Like everyone else, it is just an endless loop and I can't get logged in anymore. I Do NOT use Chrome. Please fix this issue.

Still doesn't work correctly. It works once or twice, then nothing. If I remove it and re-add it, it will work a few times then stop again.

This will not work on Firefox. Once I try to verify using my CapitalOne app, the extension hangs or sends me on a never-ending loop of trying to verify. I do not use Google Chrome as a browser.

Eno might actually be great, but I can't find it. Doesn't show up on my browser. Is this a joke? Keep getting notifications about using this add on, but no matter how many times I download it, it's never there!! Stupid!!

Eno was working just fine in my Firefox browser since installing it a couple years ago, then recently it began to consistently malfunction. Since about May 2020, clicking the Eno icon brings up a "clueless Eno" that can't determine it's already been installed--despite the 20 or so preexisting virtual card numbers on file (which couldn't have been created without Eno being installed.) Stoopid Eno!

During the 1 hour, 50 minutes, and 53 seconds spent on the phone with Capital One Customer Service, the truth came out. The June 5th, 2020 implementation of the current Eno version was tailored to work just on ONE of today's top 5 web browsers--NOT Mozilla Firefox, NOT Apple Safari, NOT Microsoft Edge, and NOT Opera. Eno now works properly on ONLY one web browser, Google Chrome.

Once again, Capital One, thanks for less than nothing!

Ever since the 3.5.1 update, the addon has been lagging webpages for me. It's basically unusable now until this is fixed.

this requires access to data for all websites and access to all tabs before installing it -- ridiculous and totally insecure, there's absolutely no need for them to be so intrusive just to generate a virtual number -- I did not install it

Can't login to use the app.

App is worthless. Try to log in, there always "A problem." It's been like this since launch and I don't know why they don't care to fix it. Even the link to "Manage Eno" on their website is a deadend. Don't know why a HUGE company like CapitalOne can't deploy and effective virtual numbers app when another bank I had many years ago had a terrific web-based system. This bank is idiotic for not fixing this longstanding issue if not for the sake of their customers, then at least to help minimize fraud (when permanent card numbers are compromised).

Shame on you, CapitalOne.

This is worthless. I have never got it to work with Firefox.

Used to love this extension until it stopped working a few months ago.

Now, every time I try to log in, it says "Restart your browser". I have tried fully shutting down and restarting my browser as well as fully restarting my computer, it just doesn't work.

Please fix!!

Verification does not work. Everytime pops up to remind me to use but the problem is the verification does nor work. I don't see an option to enter the CVV to verify at all

My small business card encouraged me to use this extension however it doesn't work with small business cards. It only shows my personal cards. That makes it nearly useless to me since most of my purchases are business purchases.

Errors out saying something went wrong.... I heard it works just fine on chrome but I will NOT use chrome just for this extension... You need to fix this to work right for Firefox like it did when I first got it.
