That little button has nothing to do with autocomplete

It has everything to do with avoiding any popups. Once you put in your userid, your password and click the little “Remember my password” button, that's it. No popupus, no userids, no passwords again, EVER!
So what's your problem?
You just crack me up. Here is a guy that boasted that he had removed all IE8 from his computers after downloading it, only for it turns out the lying sucker was still using IE8 anyways.
You just can't trust open source fanatics to tell the truth..ever. They will lie and cheat every singe time about Microsoft products they know nothing about, in their pathetic attempts to spread as much FUD about any Microsoft product as they can.

Not really. Because it's a WEBSITE feature and not an IE feature your autocomplete has nothing to do with it. You can go to a login website for the first time with autocomplete enabled and check that box and still get the popup. They have absolutely nothing to do with each other, nothing about that checkbox (or dropdown on FR) has any effect at all on the behavior of autocomplete or vice versa. Here's an example of the popup and the dropdown both happening at the same time completely unaware of each other:

I don't have a problem. You on the other hand have now fully established that you have absolutely no idea what in the hell you're talking about. You think website cookies and IE's autocomplete feature have anything to do with each other at all.
