Q209: Permission to execute userscripts

A209 For users of the Tampermonkey extension (version 5.3+) in a Chrome-based browser, enabling either the "Allow User Scripts" toggle (available in Chrome 138+ via extension settings) or Developer Mode is required.

Why is permission to execute userscripts necessary?

An additional permission is required due to the two-step authorization process for userscripts: the userScripts permission and either the toggle or Developer Mode. The userScripts permission alone doesn't trigger a user warning upon installation, reflecting Google's intent to ensure informed decisions when running extensions that use Userscripts.

Steps to enable
