Anyone else here not being able to middle-click a YouTube video’s thumbnail to open in a new tab? I can only do it on the video’s title now, and it’s quite annoying. I’m used to opening a few nice videos to watch in different tabs so I don’t lose them.
Edit: NiSwan’s answer fixed it for me, all back to normal.
You need to disable the inline videos. I found the steps in stackoverflow, it’s changed in your profile settings on YT.
