Works to block the ads and annotations. But now Youtube has a new thing where they force you watch a clicked video after you back out of the page. The said video will continue on your screen as a pop-up window on the bottom right corner. Pretty sneaky and a cheap shot to increase views for the Youtubers. Adblock does nothing for this....I guess it's not an ad so...

Now Youtube has a drop down portion of the screen too. Does nothing for that either. Youtube is unstoppable!

6/16:
The playing video's in the pop-up windows are back. If you view a video that was just click bait and back out of that page the video follows you. This does nothing for it.

Las páginas de internet no merecen que les sea bloqueada la publicidad, excepto por la basura de google y su política de no privacidad. Ni un dolar más a esa basofia. Viva GNU

ดีมากๆครับ Ads ไม่มีกวนในวิดิโอ ที่กำลังดู

Excellent!. I like this extension!

Es genial este complemento!!! Funciona perfecto!!!!!

Мне понравилось.

Much grateful for the methods described

Que dire sinon que ça marche ! Fini les interruptions intempestives tous les quart d'heures pour des produits ou des services qui ne m'intéressent absolument pas !
What could I say, except that it works fine ! No more irrelevant ads for products or services for which I really don't care !

I love this extension because it works! The ads NEVER show up. I have this installed on my Chrome AND Firefox. 5 / 5 Stars

Seems to be working well, no ads encountered so far

Я уже и забыл, как выглядит реклама на "Ютюбе". Низкий поклон вам, разработчики.
