HTML font weird behavior in Firefox

I have noticed this weird behavior in firefox, it seems like font have some colorful noise. The example is shown in the image开发者_如何学C.

Does anyone know how this can be solved? With some CSS media type (which now is screen)?

I'm using firefox 4.0.1.

Any help is appreciated.

You're seeing subpixel font positioning and rendering. I assume that you're on Windows, which is why you only see it with Firefox 4 (and IE9, if you try that). On Mac, Firefox has done this for a very long time.
