Blocking advertisements and not having to cache personal data allows the browser to load pages faster. At the same time, the user can independently choose which kind of content will be blocked and which will not. Such a flexible setup allows you to get rid of unwanted ads only.
Focus uses Yahoo Search as the default search engine, which is clearly not to the taste of most users. The creators of the browser explained their decision by the fear of surveillance of customers by government agencies. Whether there were sufficient grounds for this, it remains only to guess.
At the time of publication, Firefox Focus is available for download only to iOS users from the USA. There is no information about the timing of the appearance of the web browser in the Russian App Store, as well as in the Android and Windows Phone versions. It is possible that Mozilla developers, considering other operating systems insufficiently protected from the point of view of external penetration, preferred to postpone the release until better times.
