One thing that has always made Chimera unusable for me as a browser has been the lack of an option to specify a minium font sizes, meaning many fonts displayed far too small for my limited eyesight.
On a hunch, I added the following line to the prefs.js file:
user_pref("font.minimum-size.x-western", 14);You can change 14 to any font size, and Chimera will never display fonts smaller than that size, regardless of what the page specifies.
