I'd never use youtube without this.
Segments can be a bit overzealous. I'm surprised by what gets upvoted sometimes. "Highlights" in particular are just confusing more often than they're useful IME (why would anyone want to skip the first 10 seconds of Old Town Road?), but it's more of a problem with categories that you might generally want to autoskip, but sometimes have segments that don't fit the category rules.
So, this is a bit more of a compromise than traditional adblockers are. But I'd rather occasionally hassle with unskipping a segment than ever hear an ad-read for a VPN ever again. It's a net positive by a huge amount. Thank you Ajay and everyone who tags segments.

This extension does what it claims to be, but there's one issue on the mobile version. When I'm watching a video on full screen and if that video has a sponsor part, as soon as the video comes to that part the extension is forcing the player to exit the full screen.

can't live without this anymore. just wish the extension worked a little more silently

This extension is one of the best things after uBo, it is just superb, but there is one thing that bothers me, recently a rewatched a video and there was already a sponsor segment marked, but it was wrongly timed, I corrected it, but my marked segment was not saved even though it was the correct one, I think this should be fixed, even though I downvoted the wrong segment, it is the one that still appears in the video.

Now it does not show and skip segments with default ad server. Even with uninstalled other addons. Have to change it myself. Thanks to other user in comments !

It works well and saved me a lot of time, although I found a really annoying bug that stops the progress bar from working when using it on Firefox. It won’t show any elapsed time and will only indicate your position in the video when you hover over it to see the red dot. The only fix I’ve found is to completely reinstall or disable the extension, and even then, that only works for like an hour or two. Please fix this! I don't wanna go without the extension but I can't STAND this bug!

This is raw, feels wrong to use.

nice addon, but unfortunately the "vip users" oftenly downvotes other people's suggestions from their alt accounts just to place their own segment mark on exact same spot and farm the views and likes

К сожалению ютуб стал медленней с данным расширением, слышал они специально противоборствуют подобным блокировщикам и замедляют что бы отключали. Пришлось отключить и надеяться на обновления с обходом замедления.

the extension works well but rarely instead of skipping it goes to the start of the video. i like to use it to watch youtube in pop out when im playing games and not having to skip stuff manually. only "Auto Skip" can be used when im playing games and sometimes "Filler" runs on too long but i dont want to skip it. i think something like "Auto 1.5x/2x Speed" would be nice

do NOT use youtube without SponsorBlock. Despite the name it does NOT block: it hides. It's akin to CSS "blocking" which also only hides. It hides by skipping. The sister extension solves clickbait. Continue to win the war on ads Privacy HarM with privoxy for firefox.

The SponsorBlock defaults are unacceptable. Enable EVERYTHING to skip. Disable self promotion. Win.

Really love this extension - it greatly allows to save time . And option to add "sponsor" "remember to subscribe" timestampts etc is very easy to understand.
I only have one question- would it be possible to add another category for "health hazards" like epilepsy?
I seen few videos that have flashy lights that can cause epilepsy attack and no warning and thought about option to report a fragments like that for other safety as well

While it doesn't catch everything, it catches most, great add-on to use

would be cool if we'd get the same functionality as the chrome version has like blocking intros/bad filler jokes/recaps/previews
