I use uBlock and haven’t had a problem yet. I also use Enhancer for Youtube which also does ad blocking plus allows customization of your youtube viewing/experience.
I won’t do the 1 minute ad to watch a 10 minute video. Will do without if need be. I have a youtube downloader I can try as a last resort. Might download them minus ads.
I’ve never heard of Enhancer for Youtube. Is that a chromium extension, or is it available for a Mozilla browser as well?
