この拡張機能について
Keep your screen awake exactly when you need it, without draining your battery when you don't.
Whether you are following a recipe on your phone, reading a long article, or keeping a dashboard open on your second monitor, this extension ensures your display won't time out and go black.
Features:

* Always keep this website awake: Automatically keeps the screen on for an entire domain.
Privacy First & Mobile Ready

(Power users can opt-in to global permissions in the extension settings to skip future prompts).
Note: For security reasons, the browser only allows the screen to stay awake on active tabs using secure connections (URLs starting with

The permission strategy follows the "principle of least privilege". Actions that "always" apply to a URL require the user to opt-in to domain access. There is an option for users to grant access to all websites if they find the individual permission approval tedious.
