A BrowserSetting object whose underlying value is a boolean.
By default, of course, web pages can specify the fonts they want using CSS properties like font-family. This setting enables an extension to instruct Firefox to ignore the fonts specified by the page, and only use system fonts.
Its underlying value is a boolean:
true: use the fonts specified by the web page. This is the default.false: use the system fonts.| Desktop | Mobile | |||||||||||

console.log(`Setting was modified: ${result}`);
}
browser.browserSettings.useDocumentFonts.set({ value: false }).then(logResult);
