Font type/size randomly change

[MPN]

Hello.
I got a porblem with my web browser (firefox) that started last night.
For some reason it decided to change the font type and size.
But only on my facebook wall and when i search on google.
Ive tried to do ctrl+0 to reset the font size and ive been trying to change it in the options. But its still the same.
Any ideas on what it can be?

See if you have FF set to allow pages to choose fonts.

Open Firefox> Tools> Options> Content> Fonts and Colors> Advanced> Uncheck Allow pages to choose their own fonts, instead of my selections above> OK



See if that helps. A Guy
