AutoFill not working with mouse or pressing tab is a known issue on our list.

As for AutoFill not working well. Right now there is no fuzzy matching in AutoFill. This means it will fill any form field it finds an exact match for in your AutoFill store but nothing will happen if the field name is just close. Since there isn't really any standard fuzzy matching would improve things a lot here but with a decrease in accuracy. With the properly implementation we should be able to keep things pretty accurate though, something we'll be looking into for future releases.
