browserSettings.zoomFullPage

A BrowserSetting object whose underlying value is a boolean.

By default zoom applies to all the content of a web page. Using the Zoom Text Only setting users can choose to zoom only the text on a page. This settings enables web extensions to control this setting and determine whether zoom is applied to the entire page or to text only.

The settings are:

  • true: zoom applies to all the content of a web page (default).
  • false: zoom applies to web page text only.
