+Blocking-wise, this is one significant leap from [easy mode](https://github.com/gorhill/uBlock/wiki/Blocking-mode:-easy-mode). However, be ready to accept you will have to un-break web sites, though at a lesser rate than [hard mode](https://github.com/gorhill/uBlock/wiki/Blocking-mode:-hard-mode), since passive 3rd-party resources (i.e. images, css) are not blocked in medium mode.
 
 This is where you start to use [dynamic filtering](https://github.com/gorhill/uBlock/wiki/Dynamic-filtering), a feature available only when you tell uBlock Origin that you are an [advanced user](https://github.com/gorhill/uBlock/wiki/Advanced-user-features). Be sure to read [the guide](https://github.com/gorhill/uBlock/wiki/Dynamic-filtering) before, it is assumed that you understand well how dynamic filtering works in order to use effectively medium mode.
