Firefox font size control

[chilcutt.m@gmail.com]

I have a Mac Powerbook G4. About two months ago my font sizes changed on Firefox browser. I have searched and tried many firefox apps to fix the problem, but NONE of them work.
All I want to do is go back to my old firefox with normal size fonts ALL THE TIME, ALWAYS.:(

You could simply delete the prefs.js file from your profile. This will reset all preferences, including fonts and extensions. I would advise to make a backup first.
