Saves some id's and passwords but not all of them. Why?

Some sites (like and others) like PayPal, Yahoo, Windows Live and bank sites use ''autocomplete="off"'' to prevent Firefox from saving the name and the password. If a site uses ''autocomplete="off"'' then look at this article for a bookmarklet to remove that autocomplete attribute. http://kb.mozillazine.org/User_name_and_password_not_remembered https://www.squarefree.com/bookmarklets/forms.html#remember_password (bookmarklet) See also http://en.wikipedia.org/wiki/Bookmarklet
