Sometimes when I scroll up and down, the screen font gets funky.

Sometimes when I scroll down a page on a website, the screen font goes from being clear to blurry and kind of funky looking, like when you don't use Clear Type. Is there some setting I can change to prevent this from happening? With very small fonts, it sometimes becomes almost unreadable.

Hello toekneesee, try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.

You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).

Then perform these steps:

  • Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
  • In the Firefox options window click the Advanced tab, then select "General".
  • In the settings list, you should find the Use hardware acceleration when available checkbox. Uncheck this checkbox.
  • Now, restart Firefox and see if the problems persist.

Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
