Horribly unreliable. Two stars because it isn't completely broken.

I flush cookies on quit, so I sign into the same sites over and over. I *know* the URLs are right. I know it *can* find the right login form fields for these sites. It has succeeded in the past, so everything must be in place to work right. It just often doesn't fill them in. And it's not just one symptom, it's a strange mix of scenarios and reassuring feedback right before it does nothing. I love keepass, and want to love the extension, but I'm off to write a few github issues.
