Text is rendered super faintly in firefox 3.0.8

Text on some websites is rendered to faint to read. I can read it if I select it all but otherwise I cannot.

Screen shot here: ff text on Flickr - Photo Sharing!

have you by any chance changed the system color scheme off of default? i had the same issue when i decided to change my color scheme and its a simple fix inside firefox settings uncheck the check box for use system colors

That worked. All though I had to change it within about:config

Thanks
