I would like to make the arrows beside the folders larger.
The arrows used to expand/collapse the folders are a little small and I can't quite figure out how to enlarge them, or even change to another image entirely. I don't care if its a box, circle, whatever, I'd just like something a little larger to click on. If anyone has some pearls of wisdom they would be greatly appreciated!

What you should look for is articles that describe userChrome.css files that modify the moz-tree-twisty element:

Some of these expand the 'hit area' and others replace the icon. Note that you can expand or collapse a folder tree with the left and right keyboard arrows.
