I've been curious about why my browser (if that's whats causing this) does this.

I'm using Firefox and have different websites stored as the buttons below the address bar. Because I have so many, I just have the icons displayed.

Whats weird I lets say I go to Yahoos website, then to another webiste from yahoos and the open another tab and go to another website from my buttons.

If I close firefox, and come back, the yahoo favicon will show up as lets say Youtube and the ebay icon will show up as oh... lets say my istockphoto icon.

Why do they switch? The address dont change and I thought the browser reads the .ico file from the server its hosted on....
