Need to block Momo Challenge on school PCs

Due to the concerns about the Momo Challenge kids will search for on YouTube I need to block these sites and searches in our school network. I see how to block them in Internet Explorer using Group Policy but that seems to be specific to IE. How can I block them from Firefox and Google Chrome?

We use Windows Server 2008R2 and a combination of Windows 7 and Windows 10 client computers.

Thank you.

I would just block the sites in the content filer on your firewall. (assuming you have one as most schools do)

That said if you do not have a content filter you could block the IP in the firewall.
Additionally if you wanted to you can add the sites to the restricted sites list via GPO.

You cannot block searches on Youtube

Youtube has hundreds of IPs that change dynamically

The requestor said  "Sites"  and searches I was addressing blocking sites.
I personally don't know any way to block specific searches from occurring with out blocking the site or search engine it's self.

You could blacklist youtube in your gateway router as some have mentioned above.  But what about all the other stuff kids should not be getting into?

Have you thought about using a DNS filter?  Here is an article describing some reconfigured, filtered DNS servers available.   Many of these servers exist and are simple to use.  All you do is replace the DNS Server addresses with the filtered server you select.   Your school district may have something like this set up already, in which case ignore my stuff below.

When evaluating different servers, this tool from Gibson research will be helpful to determine performance information,
