It would be handy if Bookmarks Manager could click "Login" button by itself. - If there is exactly one stored password for URL, display new option "Login immediately" for this page in Bookmarks Manager, - When user clicks bookmark, after page is loaded & password is filled, if this option is turned on, Bookmarks Manager must set focus to Password field and fire KeyPress event with ENTER keyCode. Reproducible: Always 1. See Bug 592640, both suggestions are about working with stored passwords in Bookmarks Manager, 2. There may be some not user-friendly login pages which ignore Enter click in Password field... Automating them is more complex but still possible. I suggest to put handling them aside, consider this rare case later.
