Answer 1

For a fix, see the fourth item at http://www.webgapps.org/tutorials/firefox/troubleshooting/rendering-issues-and-solutions

Open the file ~/.fonts.conf with a text editor

gedit ~/.fonts.conf

then replace the content of that file with this . Save it and restart Firefox.

If you want a simple way of changing Firefox font, then use Theme Font & Size Changer extension.
