Like everyone else, this used to work and now it pops up a login window to only manage your virtual cards, the little eno window just spins waiting for login. since everyone is experiencing this issue, very disappointing they obviously did no testing of add-on for firefox. Using latest 3.6.1 version.

Fantastic and much needed idea and feature!!

However, the implementation of the idea is just awful. The add-on either:

works only sometimes,
not at all
or takes 15 minutes to load.

AND everyone providing a review are all sayin the same exact thing!!!

You would think that Capital One would want to fix that or at least "take it very seriously" I just end up using another service that actually works as designed.

This app had problems in the past, but has been working flawlessly for some time. Very helpful.

Alas, have to agree with many other users: This is Great WHEN IT WORKS, but it Too Often FAILS to work - even after an Uninstall / Reinstall.
(As an Additional "Alas": NON-Scientific testing suggests the ENO add-on works better on Browsers Other Than Firefox.)

Basically is worthless when you need it and Capital One doesn't seem to want to fix it. It'll pop up and connect immediately on pages you don't need it but on pages where you need it to operate it'll freeze up trying to connect. Even worse, if you try to disconnect the session it'll still keep trying to connect in the background until you close out firefox in the task manager. So not really worth using until they pull their heads out of the "exit hole" and fix it unless you got a lot of ram to waste as it'll keep eating up resources and not work when needed.

it does not work makes no sense

It used to work really well, but it doesn't really save your session anymore. I hope it gets updated again. The last 3.6.0 update isn't the best.

This used to work great, but then it stopped working well. There was a change where it now pops you out to a separate log in and that function is terrible. Logging in from the main browser window was much better.

Often hangs and is unable to proceed without going back into the shopping cart. I lost an order I had alerts setup for when it got in stock. Because of the app issue it went out of stock before I could fix the issues and get the virtual number. Please make this app more robust. I pay yearly for the card but this app is not there when I need it.

Did not work at all. added to mozilla firefox. Said to click to set up. I clicked. Wait. Wait. Wait. Shows Capital One/Eno small browser frame on screen saying Continuing. Come back hour later. Still says that on the screen. Deleted and reported to Capital One that is does not work.

Updated July 2022,
Um, an old problem is back, guys. It gets into a Sign In through Browser --> Login popup --> Sign In through Browser.

Based on other reviews, it has been broken on Firefox for three days. The devs released a broken product and they're not fixing it.

Would give it a negative star rating, because I've given better products 1 star.

Does not working only shows this forever.

This addon slows my browser to a crawl on various different websites. It's not worth using until fixed.

Like everyone else said, this addon makes youtube and some other websites VERY slow. I don't know what it's doing in the background but it's not good.

The Eno service by itself is fine, and this add-on works. However, this add-on seems to slow down the browser a lot. Especially YouTube.

I have never had any issues using this addon, it works well in what it is supposed to do and I love that it auto-populates the credit card info when I'm checking out on a website. However, like other reviewers mention, it creates considerable lag on some sites like youtube. Youtube videos are virtually unplayable when using this addon as it causes the entire site to lag to no end.

This app works but make sure you disable it while using Youtube due to it making that site quite sluggish. I finally narrowed down the app causing it, it is definitely Eno.

Doesn't seem to work. It can't find my phone number despite having entered it on signing up.
