How do I set Thunderbird email font size?

Hi Please be more specific about exactly where you want to change the font. There are ways to change the font used for viewing an email, creating new emails, while creating a single email, or the whole of Thunderbird's display (Menus, folders, toolbars etc.). As examples of the several places to look - Account settings for the default fonts when composing, Tools/Options - Preferences - Display for viewing emails, or Format at the top of an email you are creating. Thanks, Agnes
