Ok

Easy to use, Open source, and none of the problems I've had with previous password managers

Very good and the best login manager.
One missing feature for me is, when you have multiple logins for one website, it would be good if I could know that I already used that login name/pw that day.
Lets say in the manager window you have 5 logins for the same website, and you already used 2 of 5 login names that day, then it would be good if it marked that with GREEN background, showing that that login was already used today. Also would be good if it can rotate to another login credential which haven't been used on that day, and one click login button on toolbar.
Perfect extension! Thank you!

Great password manager all together. Not just this extension but the service and other facilities are really nice. It supports all your devices and browsers. If you are looking for some password manager then this is it. It is opensource and already passed 3rd party security audit. It's premium membership is also reasonable.

My new Password Manager of choice, after a decade of using LastPass, I was done with their creeping featuritis and failure to work with Firefox. Importing from LastPass took some editing of the CSV export data, but I finally managed to reach a workable clean new Vault, which I incidentally sorted better through the conversion as well. Thus far, I'm very happy with the much lighter lean interface of Bitwarden. A little worried about its development though, since not many are actually responsible fot its code, as far as I can tell. If the main dev dies, we're shit out of luck when for example Firefox changes stuff again.

Possibly the best password manager around.

It just works, is pleasant to use, and is open source. (Also self-hostable, encrypted, no-ads, and straightforward pricing for premium features if that's what you want – I don't use any premium features though!)
