Font looks weird in firefox

more options

I recently restored my windows 7 version and downloaded the newest version of firefox. All the font in firefox looks smudged and is not crisp an clear at all. I have tried unchecking the hardware acceleration tab in options but it still isn't working. Any help would be greatly appreciated.

Can you attach a screenshot?

  • Use a compressed image type like PNG or JPG to save the screenshot
  • Make sure that you do not exceed the maximum size of 1 MB

Do you have ClearType enabled for all programs in the Windows settings? Win7: Control Panel > Personalization > Window Color and Appearance > Fonts > "Adjust ClearType text"

Try to create a new Boolean pref on the about:config page via the right-click context menu with the name layout.paint_rects_separately and set the value to true and leave hardware acceleration and Direct2D enabled.

  • layout.paint_rects_separately = true
  • gfx.direct2d.disabled pref = true

That way you still have the benefit from hardware acceleration, but may not suffer from rendering issues.

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.

The clearType text solved the problem. Thanks a lot for the support.
