I was looking for an extension that would allow me to block annoying videos that would automatically play in the background on news sites but I didn’t want to go through the hassle of having to whitelist all the websites where I don’t want videos and images to be blocked. What makes this extension great is that you can choose to use the blacklist feature instead of the whitelist feature by unchecking “Block all sites except those on whitelist” in the preferences of the app. It’s exactly what I’ve needed. I’m running High Sierra so I can’t confirm if this works well on Mojave or Catalina but other than that, this has been useful.
