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.

I installed it 2 months ago (didn't have to disable/remove any of my plugins or extensions or pop-up blockers, I just searched for Eno in Firefox add-ons & installed on Windows 8.1 w/ Firefox 72.x, later Firefox auto updated to 73.x, 74.0 w/ no problems to virtual card# use) - easy install, no need to restart Firefox or laptop. It's worked great for me since then on many online retail sites. When using for the 1st time on a new retail site, it requires 2 factor authentication w/ your cell, after that it'll save & reuse the newly assigned virtual card# for that site (it also auto fills in the payment form). Each site gets it's own different virtual #. You only have to type in your name on the payment form.

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.

to eveyone that cant get it to work. 1) remove any popup blocker. 2) drag and drop virtual cc # onto wherever you are putting the virtual number. 3) i did the later and then rebooted my computer

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

doesn't work

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.

Seems like a good idea.

Jan 27, 2020: Works great and easy to use.
Have used it on all the websites where I have subscriptions with no issues. Add on will autodetect a page where CC info is to be entered and launch itself to allow you to link / generate a unique CC number for that site. Websites where it has worked flawlessly: Amazon, Netflix, PayPal, NY Times, CuriosityStream, Comcast. On most of the above, the CC info auto-populated into the correct fields, and on the couple of instances where it did not, the handy "Copy" button allows you to copy / paste the info where needed, or you can enter manually if you choose. The settings cog, which leads to Capital One's VirtualCards website itself also works very well to allow you to see / manage your virtual CC numbers.

Highly recommend this addon.

Works Great!!
