For those wondering or rating low complaining that it doesn't work on YouTube (anymore). Know this.

YouTube is a constant race with ad blockers. YouTube is spending loads of resources constantly, as in possibly more than once a day, changing their code so the existing ad blocking filters doesn't work. The people behind these filters then update the filters and it'll work again. There will be a period of time when the filters haven't been updated yet at source, and you won't be able to access YouTube with the extension on. That is just the nature of the ad vs ad blocking world you're in.

The extension (and associated filters) work, you just cannot expect it to work 24/7 against a website with the resources to actively block it.
