We are currently evaluating Passwordstate for roll out.
The Password extension is great, but I think it would be better, if you have the option to turn off auto complete, as it sometimes tries too hard to fill forms. Furthermore you don't have the option to decide which account should be used for some form. Maybe you have access to a global admin account, but want to use a personalized account instead?
Better is to click some button or press some key shortcut to fill the form. I think of the way like Enpass does it, if you don't mind to try it out.
Cheers
