Default font and Size

Web pages are usually displayed in the font and size specified here.
However, web pages can override these choices unless you specify otherwise
in the Fonts dialog. Click the Advanced... button to access the
Fonts dialog and to change this and other fonts optionspreferences.

Fonts Dialog




1. From the Fonts for drop-down list, choose a language
group/script. For instance, to set default fonts for the West
European languages/scripts (Latin), choose Western. For a
language/script not in the list, choose Other Languages.

2. Select whether proportional text should be serif (like "Times
New Roman") or sans-serif (like "Arial"). Then specify
the font size you want for proportional text.

3. Specify the font to use for Serif, Sans-serif and Monospace fonts.
You can also change the size for Monospace fonts.







You can also set the minimum web page font size. This is useful to
prevent sites from use overly small fonts that are barely readable.




Allow pages to choose their own fonts, instead of my selections
above

By default Firefox uses the fonts specified by the web page
author. Disabling this optionpreference will force all sites to use your
default fonts instead.




Character Encoding

The character encoding selected here will be used to display pages that
do not specify which encoding to use.



Colors Dialog



Text and Background

Here you can change the default text and background color to be used on
web pages that haven't specified that information. Click on the color
samples to select colors.




Use system colors

Check this optionpreference to use the colors defined in your operating
system settings instead of the colors specified above.




Link Colors

Here you can change the default colors for Web links. Click on the color
samples to select colors.




Underline links

By default, links are underlined on web pages. Uncheck this optionpreference
to disable this. Note that many sites specify their own styling rules
and this optionpreference has no effect on those sites.
