Best adblocker ever. I wish Google would enable extensions on Android so that I can use this on my phone too.

Отличное расширение. Блокирует рекламу на youtube, легко выбрать блокируемый элемент, временно включить/отключить.

Awesome pop up blocker unfortunately removed by google for the f4scist reason of doing excellent what it says it would do. The endless stream of stupid random commercials in youtube. Time to switch to firefox for my main browser ..
