 The main advantage of AdGuard standalone programs over browser extensions is that the programs can block ads in every browser and in almost all apps. You may use different browsers at the same time, the app will filter ads and online threats in all of them equally well.
 
 The second difference is that the possibilities of extension-based ad blockers are strictly limited by browser guidelines. The browser extensions have to conform to the policies of the browsers, where ad blocking might be restricted. Thus, some types of filtering rules are not supported by the extensions. The functionality of the desktop apps is not limited, so they have a better filtering quality.
