OH WAIT no yeah it does work on firefox, it's just that the scrubber hitbox was small and kinda near the bottom of the circle graphic :V
WHAT, how?!
I'm confused at how/why changing the width of the resizeable element shows different elements below
this takes advantage of word wrapping. the resizable element also shrinks the div next to it, which contains a bunch of inline-block elements that are right-aligned. as the div shrinks, a different element wraps to the top right corner.
