Printed words blur or letters are missing on websites and news articles
When I go to homepages like http://www.aol.com, printed words are smeared with blurred letters or letters left out. The page looks like a bad printer about out of ink. I do not have this problem with Internet explorer or Chrome. I am using Windows 7 and this problem appeared just the past month. I contacted the manufacturer of my computer with the problem and they said it was a Firefox issue and not a computer issue after spending an hour on the phone with them where they tried to update my video drivers etc. This same issue appears on any website or news item I click on. Sometimes moving the curser over the words clears them and sometimes it doesn't. It gets worse when I scroll a page.

Try to set the gfx.content.azure.enabled pref to false or if this didn't help disable Direct2D by setting the gfx.direct2d.disabled pref to true on the about:config page and leave hardware acceleration otherwise enabled.
That way you still have the benefit from hardware acceleration, but may not suffer from rendering issues.
You can also try to uninstall Windows update KB2670838 if you have this update.
Try to disable hardware acceleration in Firefox if the above didn't help.
- Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
