Is Дзен без рекламы бесплатно | PromoFilter safe?

Low risk

The extension fetches CSS from storeboost.ru every 2 hours and injects it into Yandex, Dzen and Mail.ru pages.

The extension hides ads on Yandex, Dzen and Mail.ru pages. Its service worker downloads a stylesheet from storeboost.ru, sending a persistent random client ID in the request, and injects it unchecked into matching pages, including webmail. The stylesheet currently served only contains ad-hiding selectors.
