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.

It's very useful when it works. However it doesn't work 40% of the time. Sometimes it opens right when you need it, sometimes it won't open when you click it, and sometimes it just hangs at a loading screen. Very frustrating

Doesn't always open in Firefox to create new virtual card.

Increases CPU usage on some sites when moving the page, and has issues with login flows. Other than that, works well.

This add-on just keeps getting better! It understands web pages faster and makes the whole process seamless and did I say FAST?!! Thanks for the great peace of mind, ENO!

While I like it when it works, it doesn't work half the time. It's had the exact same issues for years. Sometimes it will just sit there like it's signing in, only it never does. Other times it will ask you to login, and then the login box pops up and immediately disappears. I've witnessed these same issues on more than one computer/browser.

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.

Just doesn't work - tries to login and either the login screen disappears or get a message saying "Something went wrong"

Doesn't work, calling tech support didn't help.

It's been better on Firefox lately but still freezes sometimes and stops working. Works about 80% of the time though.
