Zoom is a feature which allows you to increase or decrease either the size of a web page (Page Zoom, which is the default zoom) or the size of all text displayed in a web page (Text Zoom) in order to improve readability on a website basis. This article explains how to zoom in and out per website and describes the zoom text settings.

  • If you want to set the default zoom level for all websites, use for instance the NoSquint add-on.
