I am using Firefox 23 and Ubuntu 12.04 with Unity.
Today, I was dealing with font configuration to make them look like sharper and less blurry. After some mambo jambo, Facebook started to look like this:

I believe this is something related to msttcorefonts or Ubuntu restricted extras or some terminal commands such as "fc-cache". I do not have this problem for any other webpage.

I have been trying to find a solution to this but could not come across one at anywhere so I decided to ask here.

should do the trick.
