Scrollbars in Firefox. Halp?!

So, my whole internet browsing life I have found it endlessly frustrating that Firefox does not allow the modification of its scroll-bars. I don't care what w3c recommends at all. I just want it. End of story. I'm sure a lot of you feel that way, too! Will someone experienced help us out?

It's not within your right to modify the scrollbar colors, because the scrollbar is not a proper part of your website. You are designing the book, not the bookshelf.

Meanwhile, if you really want custom scrollbars, there are plenty of options for you out there using javascript and overflow: hidden.
