I am taking 2 stars off this add-on for 2 reasons.

First, it sometimes auto fills the needed information and sometimes does not, with no apparent rhyme or reason.

Second, the handling of multiple accounts on the same website is horrendous. It fills in the wrong password even after I MANUALLY selected the right username, and the list of credentials is in no recognizable order, making searching for credentials a real chore.

It makes you wonder whether the developers actually use it for themselves, or they would have noticed this poor design.
