And by god is that rotate feature hideous, at-least it's optional.

Okay, I edit my review and give an extra star. But you should probably add a note in the UI telling the user that they need to restart for those settings to take effect.

"Icon-style settings don't change"
If you mean changing between default/faded/etc: you need to restart FF or reload the XUL. They stay cached in memory, nothing I can do (that I know of).

"most of the icons are ugly anyway"
If you want to make an icon set and send it my way, then you may be happier.
