Product Description: 

Theme Font & Size Changer is a simple browser tool that lets you change the font size and font family of Firefoxand 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.



Main Features: 

  • Zoom: This is a global zoom feature that enlarges/zooms both Firefox itself (including buttons and icons), and web page content simultaneously. The default Firefox full page zoom controls can still be used independently.
