runtime_blocked_hosts doesn't work anymore

Question

It looks like that new versions of Microsoft Edge don't support the runtime_blocked_hosts JSON code anymore.

We are using the Microsoft Edge policy ADMX:

Microsoft Edge > Extensions > Configure extension management settings

with the following code for example:

{"*":{"runtime_blocked_hosts":["*://*.importantwebsite.com","*://*.importantwebsite2.com"]}}

This should block extensions altering webpages but doesn't work anymore. Extensions are still enabled and alter the blocked webpages. It did work before.

Tested with: Microsoft Edge, Version 105.0.1343.33 (Official build) (64-bit)

Answer 1

... a lot of instructions online are out of date, even pages in Microsoft Learn,

When dealing with group policy, I think you'll find that the policy documentation page is the most up-to-date. There have been cases, for example, where the documentation contains different text from that in the GP editor, and it's the documentation that wins. Let this be your bible: Microsoft Edge Browser Policy Documentation | Microsoft Learn - just check the publication date below the heading.

Answer 2

Thank you for your reply Paul.

I don't have the time now to test different installations but I did some testing and it looks like that a lot of instructions online are out of date, even pages in Microsoft Learn, for example this JSON code is incorrect and not working:

{"*":{"runtime_blocked_hosts":["www.microsoft.com"]}}

source: Use group policies to manage Microsoft Edge extensions | Microsoft Learn

{"runtime_blocked_hosts": ["*://*"]}} for example did work, but what I noticed here is that when you visit a page you still see the extension active, normally it was turned grey so you notice that an extension is disabled on that page.

But it's fine for me to have it working now. I will leave the rest to Microsoft ;-).
