I primarily use Firefox at my Windows machine but in Mac i use Safari ( why? ) . But there are multiple things i dont like about Safari than Firefox. One of them is how Safari shows popup confirmations to remember passwords . Safari doesn’t let you go past the password page till you decide yes , not now or never in its confirmation popup. I dislike this. I love the way Firefox handles this. In older version of Firefox such popup were there but in latest ones its removed with a pretty good banner at top which appears till some time after you passed the password page. Safari behavior is specially annoying when you ask Safari to remember the password and it happens to be the wrong password. ( so may things so many passwords you know ). The way Google Chrome handles is the advanced one among all the browsers i have seen. Its very intelligent. 

Safari and Internet Explorer match in this case because latest version of both Browsers use similar popups where your input is a must to go to the next page.. Safari and IE friends . Seems unconvincing huh..
