Network.image.imageBehavior
Background
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
0
Allow all images to load, regardless of origin. (Default)
1
Prevent third-party images from loading.
2
Block all images from loading.
Caveats
- If you set this preference in a version supporting permissions.default.image, the value will be migrated to the new preference and then cleared.
