I've used uBlock Origin for several months. It's great, and does what it's supposed to. However, the new version seems to have an odd effect when a user tries to download videos with certain downloader add-ons. I use Ant Video Downloader, and the new version of uBlock seems to not filter out empty download links on Ant as the older versions did, so when you try to download a video, uBlock doesn't filter the links so that only the direct video link is visible. This problem probably also occurs when uBlock is used with similar one-click video downloader add-ons.
