I installed this plugin purely out of curiosity, but what a time saver. Even my favourite subs have intros or in-vid ads/sponsor segments and this just flys past them. Absolutely amazing extension.

thx

It works great - however when I try to whitelist Critical Role channel (who sometimes do great ads) - I get a message saying that 'channel ID hasn't loaded - ad block interfering'.

I won't give up my ad block to use this extention. Nor does it work when I disable my ad block. Something must be wrong with this extention.

If you get annoyed at the recent rise of "But first, I have to talk about our sponsor for the day" interruptions in your YouTube videos, this add-on is an actual godsend.
Just like you should use µBlock Origin for the web in general, you should use SponsorBlock for YouTube specifically.
Just remember to support your favorite creators in other ways, whenever possible.

a good youtube extension to save time to watch even more youtube videos.

I'm glad to have found this by accident. Since installing the addon last week I have been adding skip segments to lots of videos myself and it's really satisfying to do so. Seeing the counter that shows you how much life time of other people you have saved increase with each passing day is really fun.
