What is your current setting of the gfx.font_rendering.harfbuzz.scripts pref?
Can you attach a screenshot?
Use a compressed image type like PNG or JPG to save the screenshot and make sure that you do not exceed the maximum file size (1 MB).
For Firefox 5.0.1 have about:config and Firefox 6 have about:config I attach pictures. AS You can see, with version 6, we have more options.
