Hover a thumbnail on youtube.com and click an icon at the right: "Not interested" and "Don't recommend channel"
< Feedback on YT: not interested in one click
I guess youtube is serving the old version of their site to you and my new code incorrectly detects it. I don't know how to fix it as I don't know how to switch to the old version of the site. Use the old version of the script for now until you get a new version of the site.
Old version (v1.2.28) works fine.
Thank you for this. The script wasn't working for me either, but downgrading fixed the issue.
New versions not working for me.
Old version (v1.2.28) works fine.
