Image Block adds a toggle button that conditionally blocks/allows loading of images on webpages. Blocking images results in faster browsing, especially helpful on handheld devices or slower connections.

Image Block - A Seamless, User-Friendly Firefox Add-on
Image Block is a user-friendly Firefox add-on, first introduced in 2007, designed for conditional image loading on webpages, which facilitates faster browsing and optimizes data use. It offers a simple toggle button function that is effortless to use, making web surfing more manageable on handheld devices or slower internet connections. Despite its simplicity, Image Block provides a distinct benefit of maintaining the user's privacy by blocking explicit content on webpages.

User reviews
Don't see the toolbar button. Please show us how to activate this add-on in large and clear images. The images used now are 240 x 180, way too small to see anything. And show us where the button should be and how it should look like.
