In Microsoft Internet Explorer for Windows versions 5.0 and above, choose Internet Options from the Tools menu, then choose Accessibility from the General tab in the resulting window.
In Microsoft Internet Explorer for the Mac versions 5.0 and newer, choose Preferences from either the Edit or the Explorer menu depending on which Mac system you are using. Then select Web Browser from the side tabs and Web Content from underneath that.
In Netscape Navigator versions 6.0 or above, choose Preferences from the Edit menu (from the Netscape menu in Mac system X) then Appearance from the side menu and then either Fonts or Colours.
