Scrolling of pulldown menus in preferences component is broken, and has been for a while now (since the major UI changes to widgets in preferences sometime since M13). Basically, I am unable to pull the scrollbar down, nor to scroll very far or very effectively by simply moving the mouse (I have a fair number of fonts on this system, so I need to scroll a ways through the list). Clicking on the up or down arrows of the scrolling area doesn't seem to register any sort of mouse event, and pulling the scroll bar doesn't seem to register either. I can still set other fonts by editing the prefs file by hand, but it's a pain. Scrollbars on pulldowns and other UI components in all other parts of Mozilla seem to be fine.

Yeah, I hope someone fixes that soon. *** This bug has been marked as a duplicate of 26508 ***
