On certain webpages (google and facebook), the fonts are not rendered correctly. See screenshot for example.

setting gfx.use_text_smoothing_setting to true did not work; setting ayers.offmainthreadcomposition.enabled to false did not work; dis- or enabling hardware acceleration did not work.

I have cleartype smoothing on windows vista and only firefox has a problem.

Please help, thank you
