This feature was great when it was first implemented but it seems to be increasingly unusable. It flatly refuses to generate passwords on many sites seemingly because there is a flag set in the textbox's code disabling auto-complete. It won't allow you to customize the types of passwords that are generated e.g. length, complexity, excluded characters, etc. This wouldn't be such an issue if there was a way to manually generate a password but there seems to be no tool for this anywhere in the settings and no plans to add this feature. I wouldn't be so frustrated if I didn't actually like and actually use the password manager but I do. I rely upon it almost daily and it is extremely disheartening to see it repeatedly confounded by poor design and implementation.
