Note: It is possible that your school, university, and companies are using the Turn Off the Lights browser extension to get you the best web experience in Google Chrome. And force to install the Chrome extensions you do not want. That manipulates your web browser settings.

The other situation is that you installed some bad software from the internet such as a cursor changer, flash downloader, video downloader, etc.

And in this situation, it is safe for the user of this computer laptop. Then you can see this message that the web browser is managed by an administrator. For example, the IT personal can block access to YouTube or another video streaming service. And the IT personal can adjust and block certain parts of the web to keep the employer-focused.

Then this computer has access to an own private network (or even VPN) to connect with the business or school resources (link to intern tools or library).

If the computer laptop is from the company where you are working (work, school, university).

There is 2 kind of situations you get this message. Do you get these Chrome extensions installed by administrator message in your Google Chrome web browser? It is not the fault of the free and Open-Source Turn Off the Lights Chrome extension.
