When i go to watch a Youtube video it will play for 50 seconds to a minute and a half. Why is it doing this? I have cleared my cookies and all other browsing history and re installed chrome and it still doing this.
I'll add this as an answer because it turned out to be the cause:
The problem is that since the first week of October 2013 YouTube freezes its playback after 1 to 1,5 minute. I found that the most likely cause of this freezing is Google's own Chrome Toolbox extension (it was for me). When disabling this extension the playback of YouTube continues as normal.
I have also found that none of the settings in the extension have any influence on this disruption. Because the last update of the Chrome Toolbox extension (1.0.32) is of May 2013 the cause has to be found in a new Chrome update or YouTube. As of half September Google has made a lot of changes to YouTube (for example removing the old subscription box). Also as of last week my videos start muted (needing to adjust the volume slider to get audio) So maybe Google is tweaking YouTube with some bugs as a result.
We need to wait for a fix from Google while keeping the Chrome Toolbox disabled until then.
Here's a hotfix:
Add two forward slashes before line 157, as so:
//.addEventListener('mouseout', hidden , false)
Commenting out this line removes the error.
