This extension does what it promises: it will simply block all sponsorships and annoying parts of the YouTube video for you.

Good plugin but automatic skipping on videos doesn't work unless I reload the page. I am on Firefox.

Edit: I fixed it by changing the version of Enhancer For Youtube, thanks to the devs for telling me.

If you're skipping has stopped working then it means you have YouTube Enhancer.

Read the dev comments and install the version of YouTube Enhancer that doesn't eff up SB.

I like thise addons. I like Mozilla, fundation, and Brother Firefox. Good job

YouTube update caused the extension to not skip segments anymore. Needs a fix.

Update: Fixed, Firefox & Enhancer for YouTube had received an update, thus this extension also works again.

The latest 2.0.128 update to Youtube Enhancer seems to conflict with SponsorBlock as the latter no longer skips skippable segments in videos when 2.0.128 is installed. I installed the previous 2.0.126.1 and this fixed it. Just posting here in case someone who uses both sees that SponsorBlock no longer works and thinks it's SponsorBlock's fault, it's not.

This is the single best add-on for YouTube. I just had to write a review to express how incredible it is. There are so many videos/channels that I stopped watching because I was tired of all the sponsored segments interrupting everything. I would have to scrub through them, tediously. Now, it just skips right over them no problem. Truly amazing!
