Until recently, this preference determined whether or not images loaded in the browser. Specifically, it allowed the user to allow all images, allow all images except third-party images, or block images entirely.

This preference replaced advanced.always_load_images when Mozilla hit Milestone 16 in June 2000, but was replaced by permissions.default.image in December 2004.

Possible values and their effects


Allow all images to load, regardless of origin. (Default)


Prevent third-party images from loading.


Block all images from loading.


  • If you set this preference in a version supporting permissions.default.image, the value will be migrated to the new preference and then cleared.


Mozilla Firefox 1.0.x

The checkboxes labeled “Load Images” and “for the originating web site only”, located under “Tools → Options → Web Features”, set this preference to 0 and 1, respectively.

Mozilla Suite and SeaMonkey

The radio buttons labeled “Do not load any images”, “Accept images that come from the originating server only”, and “Accept all images”, located under “Edit → Preferences → Privacy & Security → Images → Image Acceptance Policy”, set this preference to 2, 1, and 0, respectively.
