Disable video autoplay on LinkedIn
LinkedIn (recently) included a feature that starts autoplaying videos on your timeline as you scroll then into view. In case you were wondering (as I was) how to prevent those annoying videos of/posted by Brett-you-know-who from autoplaying on your LinkedIn time line - wonder no more …

From your feed …
You will need to navigate to your profile to access your settings (lame, I know) - click on your profile pic to get there …

From your profile …
Next you need to access your settings (gear icon - top left) …

From your settings …
Locate the menu item that reads "Video Autoplay" …

From Video Autoplay …
Disable (or, at least, don't let Brett eat your mobile datas - you can restrict it to wifi only) …

We're done here!
