Here is how it looks on my machine with firefox:
ON:
OFF:
Here are the direct links. you see the difference better, when you download them and switch between them in an image-viewer or have them in different browser-tabs:
ON:

OFF:

You see, that the menu and the addressbar is exactly turned around. with cleartype on the letters look like cleartype is off. firefox is not the only example. i have the same results with other menus, for example the popup-menu that appears, when i right-click on the desktop.
for me it is distracting. might be, because cleartype isn't configured correctly, but anyway, this shouldn't happen. off still means off
so there seems to be something wrong somewhere.
thanks and cheers!
