THUNDERBIRD USERS PLEASE SWITCH TO THE NEW THUNDERBIRD VERSION BY BELOW URL: https://addons.mozilla.org/en-US/firefox/addon/theme-font-size-changer-for-tb/
Theme Font & Size Changer is a simple browser tool that lets you change the font size and font family of Firefox and several other Mozilla products. 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, font family, and other changes are applied instantly 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:
