+## Youtube links doesn't open youtube app (Open links in external apps)
+
+Cromite blocks the ability to open apps from the web by default.
+
+The reason for this is that, together with the app to be opened, information may be passed on and cannot be filtered out: for example, youtube links definitely send the url of the video, but not necessarily other data. The other information could link your web browsing with that within the app.
+
+It is however possible to disable this behaviour and allow apps to be opened.
