I use Firefox in Windows just fine. When I try to use it in Linux, the little arrows at the top and bottom of the scroll bar are missing. Also, the behavior of the scrolling is different: in Windows, when I click in the scroll bar anywhere below the bar-that-shows-where-on-the-page-I-am (I don't know what to call this), the page scrolls approximately one screenful. In Linux, the page scrolls porportionatly to the distance from that object that I click. In order to scroll a page in Linux, then, I have to guess and click very close to that object, and usually the page scrolls too far. Personally, I would say the scrolling behavior in Windows is superior to that in Linux.

Is it possible to get the same behavior in the Linux version, in addition to the increment arrows at the top and bottom of the scrollbar? Why would there even be two versions??
