Comment 3 for bug 112514

Yes I do more or less,
because I found some way to compensate. I use nautilus as file manager and set the font there on a 12 so it looks like a 10 on the xfce. Then I changed the xfce System Font to 10 and the font in Firefox shrinked to nearly the nautilus desktop size. So it is still a bit larger but not as bad as it was on my screenshot.
Thanks for your interest
