Internet Explorer Content Manager (Embedded URL Codes)

Dear Virtual Dr community,

I've been using Content Manager in Internet Explorer for our call center to restrict certain websites.

One of the websites I have on my allow list is GSMArena.com but on a few of their news pages, there're youtube links added as embedded codes and within them, they can be used to search other videos which isn't productive.

I've tried adding youtube.com and .co.uk to the "Restricted sites" under Security tab and 'Never' to Content Manager which doesn't work.

Alternatively, is there an addon that can be password protected to whitelist sites with Flash content since our homepage contains Flash.

If you want to restrict access to only a few sites, use a HOSTS file
