Toolbar customization

I'm really new to all this. I've just discovered Firefox. But already I've hit a big snag. There is no provision for rearranging tool bars, as in IE. After some reading, I found that there used to be "grippies" as they call them, for moving the tool bars around....and this feature was removed?? That baffles me....why would this most basic of features be removed? Some more searching and I found an extension which claimed to be able to put this function back, but it's only compatible up to FF 1.5. Well, I hope I put this suggestion in the right place. Please put this functionality back.
