This extension does not work on sites with CAPTCHA. Had to remove from my browser to use any credit card at my grocery store.

Always use ENO FIVE stars but not now. I can no longer sign in from browser since last firefox update. Put in name and password to sign in to ENO, send and it loops back to "sign in with browser". In the upper left corner of my desktop a small window opens and closes, too fast and small to note anything particular about the window. Have all permissions, cleared all cookies, no hope. Please fix.

Just called CapOne and was told they are no longer supporting ENO for firefox. SAD.

Unable to log into add-on with Firefox versions 85.0b+. The developer needs to address this before the next public release of Firefox drops.

Stopped working in Firefox. It no longer lets me log in. There's no error. It just goes back and tells me I need to log in using the browser.

Doesn't sign in anymore. No other way to make virtual card numbers. This app is a pile of garbage.

Nice while it worked, but then login stopped working - I'd log in using the popup window and it would have no effect so I could never get a number. Needs more QA, apparently.

I used it 1 time and worked fine. Now, not able to use it a second time for a different account/store.
"KEEP YOUR CREDIT CARD NUMBER TO YOURSELF
Eno appears at checkout and provides a unique virtual card number only for that site, allowing you to shop online without exposing your actual credit card number." Did/does not appear.

It seems there is no way to use a virtual card number unless you are using a browser with the add-in AND you are shopping where the merchant has a window open to insert a virtual card number. Citi Cards lets you generate virtual cards and you can use that number anywhere.

For the most part, this seems to work well, but I ran into a very frustrating experience while using this with the HP website today. Basically, it would generate a virtual number, but the number would not properly populate in the order fields - this happens periodically, so the add on allows you to copy and paste manually - not a deal breaker. However, every time I would manually enter the virtual information, Eno would reset the page and default the billing and shipping address to the same thing (which I did not want), as well as either (a) remove the item from the cart or (b) add a second item, with no way to reload the page. I eventually gave up and went to a different browser and used the real card number.

Piece of crap - couldn't send an SMS text message to my phone telling me I didn't own the number!!! I've had the same number since the very beginning of cell service!!!

I used to use this but now when I try to use it I can't. It has become so hard to use it that I just quit using it

useful and works like a charm

Pretty good--awesome, actually--9 out of 10 times. One in a while Eno suggests a card that does not actually work. So I generate a new card, and it does not have a CVV #, so it doesn't work. And when it hangs, it does not give any indication of what the problem is or steps to take to unclog it. Overall, though, I love the security and peace of mind.

This is a frustrating piece of badly written software. I doubt that whoever approved it had ever used any of the apps that do this well. I have fought this thing for a year or more as it insisted on using only one of my 2 enrolled cards and never allowed an option to switch between them. I found out today after a 30 minute call that once a card is used at a business, only that card can be used there in the future. I went through 3 uninstall/installs, and even thought the setup said I'd be able to use either card, that was not true. This thing just does what it wants and has no way for a user to control it to their liking. Citi nailed the virtual card years ago, and Cap 1 should be embarrassed.

Can't get it to work. Says to sign in with the window it opens, I do that, it signs in fine in the opened window, but the plugin window just spins forever. I've turned off every security setting I can think of. Tried Eno on Brave and it worked perfectly fine, no issues.

Used to work perfectly, the last time I tried to use it Enos would not generate a security code. Great idea if it would reliably work.

Love this useful extension - now I can shop online and be certain that the merchant has only the assigned card, not shared. Works very well for creating unique card numbers.

not working on all web sites

Still not working

Originally worked well. Last 2-3 months not work at all. Now, I think I understand why not currently working. Have added on Mozilla again
