Please, please, please give an option to set the width of the scroll bar in Firefox. It's so narrow that about 50% of the time when I try to drag it down, I end up dragging down the whole window. I'm sure it's nice for those who have their smartphone welded to their palm, but some of us still use PCs occasionally, and it's so annoying I usually just use the Page Down key, making the scroll bar pointless. I can't imagine anyone with less than great vision even trying to use Firefox because of this.
