How to make Chrome Tabs Sleep?

Do you have a lot of Chrome tabs open at once? Are they all eating up your CPU and making your computer run slowly? Well, don’t worry, we’re here to help!

When you have a lot of tabs open in Google Chrome, the Sleeping Tab option will prevent your browser from consuming a significant amount of RAM. This setting is straightforward and disables any unwanted tabs or those that you haven’t used in a long time and allows the device to free up for more important activities.

However, there is no direct method to apply this setting on Chrome. You have to enable an experimental flag or use a Chrome extension.

In this blog post, we will show you how to make Chrome tabs sleep. This will help free up some of your computer’s resources and make it run more smoothly. Stay tuned for our step-by-step guide on how to do this.

What are the Advantages of making Chrome Tabs Sleep?

When you have a lot of tabs open in your Chrome browser, it can consume a significant amount of RAM. This can make your computer run slowly and can even cause it to crash. By making Chrome tabs sleep, you can reduce the amount of RAM that is being used and help improve your computer’s performance.

Another advantage of making Chrome tabs sleep is that it can help extend your battery life. If you are using a laptop or other device that runs on battery power, making sure that unnecessary programs are not running in the background can help improve your battery life.

How to make Chrome Tabs Sleep using Chrome Flag?

Chrome flags are experimental features that allow you to modify your browser beyond the built-in settings. They’re included in every Chrome release, and it’s simple to use them.

By enabling the Reduce User-Agent request header flag you can easily make the Chrome tabs to sleep. But since these are experimental features, we recommend you back up your work before continuing.

Here are the steps to enable the flag to make Chrome tabs sleep:

  1. Open Chrome and navigate to the following address: chrome://flags/ 

  2. You’ll find a long line of flags here. Search for Reduce User-Agent request header and the corresponding flag will be shown.

  3. Expand the drop-down menu next to the flag name, and select Enabled from the sub-menu.

  4. To make the flag effective, click on the Relaunch button to restart your browser.

What if the Flag started causing trouble?

If after enabling the flag the browser starts misbehaving, you can disable it in the same way you enabled it. Just navigate to the chrome://flags, search for the flag that is causing the issue, expand the drop-down menu next to its name and select Disabled.

If multiple flags are causing the problem and you don’t know which one is the culprit then reset all the flags by navigating to the chrome://flags and clicking on the Reset all button next to the search box.

Use Chrome Extensions to make Chrome Tabs Sleep


Tabby is a Chrome extension that allows you to control when and how your tabs go to sleep. It’s very user-friendly and has a lot of features, including the ability to whitelist certain sites so they’re never put to sleep.

This is an AI-powered tab manager that gives users the power to manage a cluttered Chrome session. It will close needless tabs and save a log of them for later use.

Here are the steps to install Tabby:

  1. Open Chrome and navigate to the following address:
  2. Search for Tabby in the Chrome Web Store and open it.
  3. Click on the Add to Chrome button to install the extension.
  4. Once it’s installed, click on the Start button.



The Snoozz extension is great if you use tabs to keep track of your tasks. You may snooze individual tabs or an entire window full of tabs, and have them activate at a time that’s more convenient for you. When you’ve set the snooze period, the tab will be shut and reopened.

Don’t worry, snoozed tabs can be seen in the Nap Room; you may rest confident that your tabs haven’t vanished.

You can enable the Snoozz extension by following the same steps as the Tabby extension.
