@catsalad @mozilla @torproject @eff if you want to use chromium still, you can block ads on the dns level
disabling javascript by default should block most ads too
if you just care about youtube, (according to a friend) youtube uses ads.youtube.com to serve ads, so just mapping that to 0.0.0.0 should work
also, I highly recommend using a privacy-friendly frontend like invidious rather than using youtube directly
if you're a creator, I recommend mirroring your videos to a peertube instance
@nemo @catsalad @mozilla @torproject @eff You can also install the ublock origin lite variant. They even share most of the name.
