The uBlock ad blocking plugin is practically the best of its kind, as it consumes less resources than the competition. This has been proven by tests.
For unknown reasons, the plugin does not include some blocking filters. Because of this, about 60% of ads are blocked, according to checkadblock.ru.
It is possible fix:
1. Go to the uBlock settings panel.
2. Open the tab “Filter lists”.
3. Find and expand the category “Region, languages”.
4. Check the box “RUS: RU AdList”.
5. Apply changes.
Done, 100% ads are now blocked. You can check at checkadblock.ru.
