All videos on a website start playing

[xetmarcr]

This just started happening a few days ago: On any website that has multiple videos available, they all start playing automatically as soon as the video loads. So, I have to locate & select each one manually to hit 'pause' otherwise the audio has them all talking over each other.

Is there some setting that can prevent the videos from starting automatically? Before this started, the videos would load and wait for me to hit the 'Play' button.

By the way, Safari>Preferences>Security shows the Internet Plug-ins setting is to NOT allow plug-ins.

(I'm on a 13" rMBPro running El Cap 10.11.1, Safari v9.0.1)

Thanks for any help

I've solved the issue by uninstalling the ClickToFlash plugin and installing ClickToPlugin instead.
