Until yesterday, I gave this extension 4 out of 5 stars, but today I only give it one star. Firstly, because the ad block function is gone, because with diligence this can also be achieved, see u-Block. Secondly, the autostart suppression doesn't work properly because the videos still start on their own. I hate it like the plague when the videos on YouTube start by themselves, this also applies to Playlist. I want to have full control and decide for myself when the video starts. A little tip on the side, Firefox is a browser that is independent of YouTube, so you can safely ignore YouTube's adblocker policy. The manifest version 3 only applies to Chromium-based browsers, and Firefox is not Chromium-based and does not have any built-in Google APIs like Google Chrome. Many people worldwide disregard the YouTube adblocker policy, what are the guys from Google going to do, sue millions of people worldwide?
