Being able to consume media without the fluff of sponsors, being reminded to sub, intros and outros built into the video makes this a special addon, especially when you can do it on normal videos and music videos. Not only is this a crowdsourced extension that everyone contributes to, but you can too! If you see a video not have the sponsorblock added, please contribute if it needs it!
It's fantastic at what it does and I cannot recommend it any further than the highest praise. Make sure to check out this developer's work. Very smart, very helpful and very user-friendly!

edit: removed my reference to the titles since that's from a different extension by the same developer

I just installed this and the difference is night and day. the sponsor cuts are seamless and make the viewing experience so much better. Thank you so much for developing this extension!
