How to add an extension to everyone in Chrome, Mozilla through GPO with the parameter enabled?

Question

Google Chrome

It is necessary to block video content, since now all traffic is encrypted, it was decided to block it in the browser itself, the HTML Content Blocker extension was found, which does an excellent job with this.
But here's a nuance, Google did not answer how to transfer the extension settings to another computer where the settings themselves are stored, and not the extension, and in the extension itself, find the parameter when changing the value of which everything gets up as it should, it didn’t work out, presumably it doesn’t correct there.

Answer 1

There is no such thing in GPO. This is if you only write a script that manually moves something there somewhere. And yes, the approach is wrong. Blocking traffic is done by installing a bumping proxy.

Answer 2

white list on the firewall / external gateway
, by the way, installed extensions are easily disabled
