Works great, but the company's been promising Fingerprint auth on the "X" version for a while yet there's still no trace of it.

I love 1Password and it is a great extension. The only complaint I have is no support for Touch ID on Mac

**Update: If you download the Firefox extension directly from 1Password you can use TouchID. Only caveat is that it requires the desktop app as well. But it makes life much easier for me.

I've been using 1password now for years and always worked very well for me.
Customer support is really helpful and there may be some features that aren't supported, but thats perfectly fine, since not every possible feature can be put in 1 solution.
However, I still can't give it the full range of 5 stars, since there are some annoyances with this extension that should be easily solvable.
The most prominent for me is the lack of a CAPS-lock indication in the login box, so I keep inputting the password wrongly on my laptop (which has no visible CAPS-lock indicator anywhere on the device) when the CAPS-lock is activated by accident.

(For example, I can detect it within an extension using:
var CapsLockState = false;
document.addEventListener("keyup", function(event) {
CapsLockState = event.getModifierState("CapsLock");
console.log("keyup", CapsLockState);
});
)

I would love to edit items in the addon and not have to open another page. But otherwise 100% excellent addon.

Attractive and well designed. Easy to use and feels stable.

Would be 5 stars but it doesn't link with the desktop app in Windows like the old extension. If you use 1Password just for the web, this is the way to go.
