Can My Teacher Really Close My Browser Tabs?

I think it’s worth checking what notifications you really got, but as an IT professional, I'd say they typically just block websites directly instead of controlling your tabs. It's a bit concerning if they're actually closing tabs on your personal device.

The situation is tricky; your school likely has administrative rights on your account when you log in. This can give them the ability to push software or extensions without telling you. It's a good idea to have separate devices for personal use and school to avoid these kinds of issues.

It sounds like your school has some serious control over their devices. Many schools use tools like 'Relay' to monitor student activity on Chromebooks, which lets teachers see what everyone is doing and even close tabs if they need to. If your laptop is managed by your school, they may have similar controls in place.

If you're logged into your school account on your browser, your school can install extensions that give them access to view and manage your tabs. If you play games on a different browser, they shouldn't be able to control that. But on a school Chromebook, they have full access until you sign out completely.
