The addon triggers an exercise session each time you load a page on the list. The exercise is activated everytime you visit a website whose domain (what is between http:// and .com/org etc.) contains an expression in the list below. For example, if "facebook" is in the list, the addon will block www.facebook.com, fr.facebook.com but won't block www.google.com/search?q=facebook.

You can change your preferences below.
