If you don't have the Yandex Browser and would like to try it out, you can download it from the Yandex Browser Website.
Click the "Yandex Browser settings" button
The button's icon is three horizontal lines. It will be near the top-right corner of your Yandex browser window.
This will reveal a menu with lots of options. One of them will be named "Settings".
Select the "Settings" menu item
The Settings screen will now appear.
The interface for Yandex Browser's settings will appear, with a search box in the top left.
Click "Advanced site settings"
Close the settings tab
The settings you change take effect immediately, and when you're finished changing the options you can simply close the Settings tab that contained these options and resume browsing.
