It is about blocking images from all websites with exceptions in Mozilla Firefox web browser. Using EasyImageBlocker addon, it is very simple. First, you can whitelist all websites but blacklist some. Second, in reverse, you can also block all websites but whitelist some. For example, you want to block all Facebook's images but not else; or, you want to block all images but not Wikipedia's. This simple tutorial explains both in easy way.

Now Firefox will block all images except from Wikipedia.

2) Block Some, Unblock All

The easiest example would be you want to block only images in Facebook, but not to block images outside. In other words, you want to blacklist Facebook. This is even more easy. You just need to change the Preferences to be "unblock by default" and then add a blacklist for Facebook only (
