Creates multiple virus like software applications that are intentionally hard to uninstall. Also not a reputable company, takes your information and tries to hide it from you that they do it.

Just chooses to not skip sponsors half the time and I have to skip back 5 - 10 seconds for it to skip the sponsored segment.

I had some extentions installed and all of a sudden, my youtube became boring. I found out why; For some reason youtube wasnt keeping up with my watch history. I uninstalled the extention and it was back to normal

Used to be great, turned to garbage literally overnight.

Inadequate developer.

I don't know if YouTube has done something on their end, or something went REALLY wrong with the latest update, but if I have SponsorBlock enabled, YouTube will now refuse to load anything but my subscriptions page.
It's also become exceptionally hit or miss with catching sponsored content, even when I manually tag stuff.

Edit: I re-enabled it with all other addons turned off, and it still did this, and it it was only when I turned it off when YouTube would load anything but my subscriptions page as of 9-8-2025.

wish i could leave zero stars. did nothing at all, i can only assume at this point the five star reviews are bots

its horrible i removed and its ui button thing still stayed

Does not work for an inch, it does not block any of the Youtube comercials even do they are repetitive and long lasting, some are almost 4 minutes and they follow after only 2 to 3 minutes of watching the original content.
its anoying and this Blockler is totally Useless.

Good extension. Toxic community.

it completely BREAKS youtube UI and all the thumbnails of videos that should display they automatically disappear.

Ass.

Makes YouTube almost unusable: adds a considerable delay to every UI interaction. For example pausing or resuming a video takes 5-20 seconds.

I love the extension, it is a must-have to enjoy youtube.
However, it is very broken on mobile right now.
After installing, in fullscreen, the video flips to portrait mode every 20 seconds or so. (Sometimes by itself, sometimes as a reaction to the screen being tapped).
The only way to fix it is to go out of FS or double tap to skip 10 seconds of the video.
It is incredibly annoying and by rating one star my intentions are only for the dev to give the issue the appropriate amount of attention it deserves as I am not the only one who suffers from this problem.
There is an unresolved github thread about it and there are reviews here that mention the same issue.
As soon as it is fixed, I will five it the 5+ starts this amazing extension deserves.

It use to work great but since the last update it no longer auto skips ads. I cant even get it to manually skip segments that it claims are already in the database.

It's not working anymore on youtube.

On Firefox mobile, it breaks youtube player.
Can Skip video but freeze YouTube player.
Like pause button, 10s forward -rewind, seeker ber
Doesn't work
