There are many Firefox add-ons that provides you with the means to enlarge and reduce text on web pages. Theme Font & Size Changer allows you to change the global font (using your system's fonts) and font size for Firefox itself meaning for all windows, menus, toolbars, etc. There are several other customization options as well.
Theme Font & Size Changer was created to be an accessibility aid for persons with visual impairments and for those without a perfect visual acuity, but it's also useful for Firefox users with high monitor resolution settings and wide screens.
It is also available for Thunderbird and SeaMonkey.
While Theme Font & Size Changer was initially designed to be used with Firefox's default theme, it does work with other Firefox themes but you may come across some compatibility issues. For example, some elements within Firefox may retain the (non-default) font size setting that the theme developer chose for their theme.
There are no known compatibility issues with Personas.
Get Theme Font & Size Changer
There are several ways to access Theme Font & Size Changer's menu to customize your Firefox.
Firefox Menu Bar showing: Tools > Theme Font & Size Changer
Firefox Menu Bar hidden: Alt+T > T or Alt+T > Theme Font & Size Changer
Once you have opened the options panel, simply select a value from one of the drop down menus and it will be applied instantly and globally.
A "Normal" (default) value is also provided so that you can quickly reset your settings back to default ones.
Tip: You can cycle through fonts to see how each one would look like when applied by hitting the up or down arrows on your keyboard when the font field is highlighted. Same applies to font sizes. Some Dingbats, Wingdings, etc, may temporarily freeze up Firefox while they are being loaded. It's best just to skip past them quickly.
