In this example we will implement private browsing on the + window level with tabs in one window all in either normal or private mode. + Alternatively we could implement private browsing on the tab-level, with + some tabs in a window in normal mode, others in private mode. + + Implementing private browsing is quite easy using Qt WebEngine. All one has + to do is to create a new \l{QWebEngineProfile} and use it in the + \l{QWebEnginePage} instead of the default profile.
