Why is the font size in google-chrome smaller than firefox on the same system?

Solution 1:

Each browser can fix the default font size.

In Firefox you will find these settings in Preferences -> Preferences -> content -> Fonts & Colors

In chrome (pulled from their website) :

  1. Click the wrench icon tools menu on the browser toolbar.
  2. Select Options (Preferences on Mac and Linux).
  3. Click Under the Hood.
  4. In the "Web Content" section, use the "Font size" menu to make adjustments.
