Reports suggest that Google may have implemented yet another anti-adblocking technique on YouTube. After slowing down the loading of YouTube for people with adblockers and showing ad blockers are not allowed by YouTube popups, it appears that it may now also slow down the buffering of videos on the site.

Update: the issue appears to be caused by content blockers, in particular Adblock Plus 3.22 and AdBlock 5.17. Disabling these should resolve the issue. End

Users report that the video buffer is filling slower than usual and that this may lead to video playback stopping on YouTube. In other words, the video pauses because the buffer has to load more content to continue playing.

This happens on fast connections. Users who turned off their ad blocker to play the video reported that the buffering would return to normal.

Google has not commented on this yet. The previous implementations affected only some users on YouTube and not the entire userbase that uses ad blockers.

To find out if you are affected, try playing a video on YouTube and watch the buffer. If buffering appears slow, or to slow down, then you may be affected. For affected users, video playback will catch up to the buffer eventually, which results in playback stopping.

Turning off the content blocker and playing the video is one way of finding out if Google is slowing down the video buffer deliberately.

Even YouTube Premium subscribers appear affected by this, if they use an ad blocker. Turning off the ad blocker on YouTube should resolve this as well.

What you can do about it

Apart from buying YouTube Premium or leaving YouTube for good, there are some things that affected users may do.

First thing is that it is important that only one ad blocker is enabled in the browser. Multiple ad blockers may conflict with each other.

Switching to another browser or using private browsing mode may work, at least temporarily. Google seems to test the functionality at the time, which means that other configurations may not be picked for the test.

Other than that, you may also try a new breed of ad skippers instead. Extensions such as Ad Accelerator or Ad Speedup try to skip ads or fast forward them instead if that is not possible. It is technically not blocking and apparently not detected as content blocking.

Another option is to use YouTube frontends. These ad-free privacy-friendly services, for instance Invidious, or apps like NewPipe or Skytube, give you access to YouTube's entire database of videos.

Now You: do you use YouTube?
