User Reviews
Most reviews praise SponsorBlock for effectively skipping sponsor segments and saving time, and highlight its well-made design and active community with a shared sponsor database. Users also note good performance with YouTube Shorts and appreciate manual segment addition. However, several users report stability problems after updates, including YouTube not loading or playing while the extension is enabled, plus platform-specific issues. A few dislike the new skip profile UI, preferring a simpler one-click whitelist. Overall, it’s highly valued but update stability is a concern. Pros
- Effectively skips sponsor segments across most videos, reducing interruptions.
- Saves time by removing sponsored sections.
- Well-made with an active community and regularly updated sponsor database.
- Works well with YouTube Shorts.
- Manual segment addition feature for contributing data.
Cons
- Causes YouTube to fail to load or play videos when enabled, making the site unusable for some users.
- Stability issues after updates; several users report it stops working and needs reload.
- Spinning wheel / performance issues on Mac OS after updates.
- Skip profile UI is too complex for some users; they prefer a simple whitelist option.

Once upon a time such an addon was a dream, seemingly impossible, but now it exists and I am very happy about it. Thanks to its author and everyone who sends segments with advertising and a quick transition to an important point.
