It isnt IE doing that. it is windows. its a standard XP feature called grouping... once you have enough instances of a single program (along with other programs) open to fill your task bar it will push instances of the same program into a group. this is a feature that can be turned off.

The reason i prefer firefox tabs over task bar is that it puts all my web pages in their own line up, not stacked. when i need to minize them i can just minimize the single instance of foxfire.

second (some of this is just how i set mine up) i can middle click to open a link (or bookmark) in a new tab, and middle click a tab to close the tab.

third... and one of the ones i really like is that i can open up a forum and middle click each thread i want to see. Firefox will open each thread in its own tab (without switching to them). then i can go thru the tabs reading what i want.

I know ie has comperable features that may only require one or two more clicks, but i prefer it this way.
