My Facebook fonts have been changed. Every Facebook page shows the same problems.
See the attached.
This print screen is on a XP machine. I have the same problem on a Windows 7 machine, a Samsung tablet and phone.
Noticed the Firefox tabs are effected, the Facebook dropdowns are effected,
It doesn't occur on any other web pages or programs or files. Facebook related pages only.
The Facebook screen is so messed up I can't find Facebook help to fix it .
Does anyone have any ideas.
