Software\Policies\Microsoft\Edge\DeveloperToolsAvailabilityAllowlist Description
This policy controls where developer tools can be used in Microsoft Edge by specifying an allowlist of URL patterns. URL patterns are matched against the URL of every frame on the page being inspected. If you configure this policy and do not configure the 'DeveloperToolsAvailabilityBlocklist' (List of URL patterns for which developer tools are blocked) policy, developer tools are available only when every frame on the page matches a pattern in this allowlist. If any frame does not match, developer tools are blocked for the entire page. For information on the URL format, see https://go.microsoft.com/fwlink/?linkid=2095322 . If you configure both this policy and the 'DeveloperToolsAvailabilityBlocklist' policy, this allowlist takes precedence. URLs that match this allowlist are allowed even if they also match the blocklist. URLs that match the blocklist but not this allowlist are blocked. URLs that match neither are governed by the 'DeveloperToolsAvailability' (Control where developer tools can be used) policy. If you disable or do not configure this policy, developer tools availability is determined by the 'DeveloperToolsAvailabilityBlocklist' and 'DeveloperToolsAvailability' policies. This policy applies to developer tools opened for websites, extensions, and web applications. This policy supports up to 1,000 entries. Example value: contoso.com https://ssl.server.com contoso.com/good_path https://server.contoso.com:8080/path .exact.hostname.com file://*
