Theme Font & Size Changer is a simple browser tool that lets you change the font size and font family ofFirefox. It is especially valuable tool for visually impaired people and wide screen users.

Different from add-ons that enlarge and reduce text on web pages, Theme Font & Size Changer changes the font size and font family in all windows, menus, toolbars, etc within Firefox itself. All font size and font familychanges are instantly applied and they are saved permanently and through sessions. You may assign your favorite font into your browser interface and change its size as you wish.

It was initially created to be an accessibility aid for persons with visual impairments and for those without perfect eyesight, but it's also useful for Firefox users with high resolution settings and wide screens.

While Theme Font & Size Changer was written to be used with Firefox default theme, it does work with other non-default themes, but you may come across issues where some elements within Firefox retain the (non-default)font size setting that the theme developer chose for their theme.

There are two places that you can manage the global font size and font family of Firefox via Theme Font & Size Changer:

Toolbar Button: Click on the Theme Font & Size Changer button to open up Theme Font & Size Changer settings panel.

Tools Option: Choose Tools menu from Firefox Menu Bar and click on the Theme Font & Size Changeroption. It will open up Theme Font & Size Changer settings panel.

In Theme Font & Size Changer settings panel, Font section provides fonts currently installed on your operating system. With this option set, you will be able to fine tune your font family of Firefox theme. Theme Font & Size Changer does not supply you with fonts, it allows you to use fonts that are already installed on your operating system which provides a greater selection. 

In Size section, simply select a font size value (from 6 to 80 pixels) and the changes will be applied instantly and globally.

Theme Font & Size Changer also allows you to change the global font size and font family for the user interface inThunderbird and SeaMonkey.
