That being said, there are a few things that annoy me about bitwarden.
For some sites or apps in iOS, you can launch a password manager to retrieve your credentials. This sometimes but does not always have bitwarden available.
Sometimes when launching bitwarden from an app, it will only show you the logins associated with the URI for your current page. But if you're launching it from an app you can't search for the right login.
These are small issues, which I usually mitigate by just launching a full on session of the app and copying the password.
I had to break a habit (I guess I picked it up from last pass) with the extensions as well. If you click away from the extension box, it will lose your context, and you can't restore it. I have had to restart filling out the credentials more than once because I didn't click save. Also, I think it takes too many clicks to create a new login with a generated password and save it.
Overall, these issues are minor for a good free product, and I would recommend it. I use bitwarden on FF, Chrome, and iOS, for context.
