Block video javascript from Konqueror

Hello, I have 3 questions.

  1. Can javascript video ads & other javascript be blocked from within Konqueror settings? (settings > configure Konqueror > java & javascript > javascript). I can see some javascript items can be ignored but how do I stop all javascript or javascript videos from a website?

  2. No Konqueror extensions show from window > settings > Configure Extensions. Can extensions like ‘no script’ be added to Konqueror? If so how? As nothing shows in this window, and there are no obvious options to add anything.

  3. I have previously used “noscript” in Firefox, which prevents javascript settings & video ads from playing but is this possible from Konqueror settings.
