how to change font size on computer?

[d.a.f.f.y.]

All of a sudden my Facebook page is in teeny, tiny font and I can barley read it. How do you change the font size to a normal size? I did have some relatives visiting this weekend and don't know if they accidentally hit something on the computer to cause this but it's driving me nuts! My Yahoo front page is normal along with anything else I search. It's just affected my Facebook page. Help!
Yay Louella! Thank you soooo much - it worked and I learned something new today! Thank you!

If you want permanent change font size then ->right click on the desktop ->select appearance tab then change font size.

From browser also you can do. just click Ctrl + 0 (zero) button to get to the normal size.
