I use Safari with Adguard and Chrome with Ublock on macOS and Chrome on Android with AdAway root version, and they work pretty fine for blocking ads, but these videos especially in news sites always autoplay and annoy me a bit, I think they have the same effect as the ads in annoyance level for me.
Do you know of some extensions or workarounds to get rid of them for good?
Some browser supports blocking videos from autoplaying, Firefox is one of them but maybe chrome has similar options too. Check the browser settings.
