running 12.04 and recently installed Font Manager and a handful of fonts that I use in Gimp.

After a recent reboot some fonts in both chromium and firefox are screwy.

fonts on this page are all 100% ok (www.askubuntu.com)

But fonts on these pages have changed to one of my newly installed fonts. facebook google yahoo (some) gmail

I had MyUnity installed and chose restore all default fonts, but that had no effect.

I have also recently installed font-manager

Usettings no longer launches for me for some reason.

Any help would be greatly appreciated.
