Partial content blocking
Sometimes dangerous elements from infected resources (banners, scripts, or sidebars) or mining scripts can show up on otherwise safe sites. Yandex Browser for Mobile uses an integrated security system to block these elements. The data on unsafe resources is taken from a special database compiled by Yandex and our partners.
Blocked mining scripts
To prevent miners from using your smartphone resources to earn money, Yandex Browser blocks the downloading of mining scripts from websites. Scripts can be blocked even if they're yet unknown to the browser. The browser analyzes the CPU load generated by sites and uses this data to block previously unknown mining scripts.
If you want to stop blocking mining scripts, disable ad filters in the browser.
