Fonts screwed up on certain websites

more options

My Firefox installation at work used to display all websites fine. But starting a few months ago, the fonts displayed on certain websites (that always looked fine before) started looking of low quality. These websites look fine when I look at them at home or with IE.

I've tried working with Tools - Options - Content - Fonts and Colors - Advanced but haven't found anything to help yet. If I turn OFF "Allow pages to choose their own fonts" the problem fonts are fixed, but then all pages display the same font and I don't like that.

I've even tried removing and re-installing Firefox, but that doesn't help. In fact, my computer manages to remember all my old bookmarks without my having to re-import them, so there are some settings files that are not getting erased when I re-install.

Below is a screen grab from BoingBoing.net so you can see what the fonts look like.

Does anyone know how to fix this, or how to re-set all the font settings on Firefox back to the defaults?
