By default, when you click the red ‘X’ in the corner of your Google Chrome browser, the window disappears, but the application itself often continues running silently in the system background. Google designed this feature so that Chrome-based background apps, active downloads, and desktop notifications can continue operating without requiring an open browsing window. However, this background process consumes valuable RAM and CPU cycles, which can significantly degrade the performance of older computers and unnecessarily drain laptop batteries.
How to Disable Background Apps in Google Chrome
If you want Chrome to completely terminate and free up all system resources the moment you close your final browsing window, you must disable the background app setting within Chrome’s system preferences.
- Open the Google Chrome browser on your Windows or Mac computer.
- Click the three vertical dots (the More menu) in the top right corner of the browser, just below the closing ‘X’.
- From the drop-down menu, select Settings.
- In the left-hand sidebar of the Settings page, locate and click on System.
- Look for the toggle switch labelled “Continue running background apps when Google Chrome is closed”.
- Click the toggle to turn it off (the switch should turn grey).
Verifying the Change
Once you flip the toggle, the change takes effect immediately. You do not need to restart your computer.
To verify that it worked, close all open Google Chrome windows. On Windows, you can then open the Task Manager (Ctrl + Shift + Esc) and check the “Processes” tab; you should no longer see multiple “Google Chrome” processes lingering in the background. Similarly, on a Mac, Chrome should completely disappear from the Activity Monitor, and a small dot should no longer appear beneath the Chrome icon in your Dock (indicating the application has fully quit).
When You Might Want to Leave It On
Before disabling this feature, consider whether you rely on specific Chrome extensions that need constant background access. For example, if you use a Chrome extension to sync offline files to Google Drive, receive incoming VoIP calls via a browser extension, or use Chrome for desktop notifications from messaging web apps, disabling this feature will stop those alerts from arriving when your browser is visually closed.
