How to reset type size

[wukong]

I was viewing a thread on the site El Camino Central when my cat decided to plop down in front and on the keyboard. The font size on the forum became so small as to be unreadable. This problem does not affect other websites. This problem does not appear on El Camino Central when viewed with IE. How do I get my problem which appears to be Pale Moon related fixed?

Press Ctrl+0 key combination while on the affected site. This will reset the zoom level back to 100%.
