维基百科里写到:“Adblock Plus (ABP) is a content-filtering extension for Mozilla Firefox and Google Chrome web browsers. ABP, a forked version of Adblock, allows users to prevent page elements, such as advertisements, from being downloaded and displayed."
明显说 ”阻止下载。。。“。
老外也忽悠人? 或者说Cache里的只是链接信息而不是图片文件本身?
当然也有可能俺的测试太简单,因为维基说:
How it works
Like Mozilla's built-in image blocker, Adblock blocks HTTP requests according to their source address and can block IFrames, scripts, and Flash. It also uses automatically generated user stylesheets to hide elements such as text ads on a page as they load instead of blocking them, known as element hiding.[1]
似乎对于IFrames\scripts\flash是根据HTTP请求拦截的(俺想是不让下载)。也自动隐藏某些元素加载而不是下载,如文本式的广告。
