Idle Tabs

"Idle Tabs" is a free and open-source Google Chrome extension for people who find that chrome is consuming too much system resource or suffer from frequent chrome crashing. Once installed and enabled, this extension will automatically suspend tabs that have not been used for a while, freeing up memory and cpu that the tab was consuming.

If you have suggestions or problems using the extension, please submit a bug or a feature request. For other enquiries, you can email it-gh@poziworld.com.

If you have lost tabs from your browser: there is a guide for how to recover your lost tabs.

Chrome Web Store

Idle Tabs is available via the official Chrome Web Store.

Please note that the webstore version may be behind the latest version here. That is because webstore updates are kept down to a minimum due to their disruptive effect.

For more information on the permissions required for the extension, please refer to this GitHub issue.

Install as an extension from source

  1. Download the latest available version and unarchive to your preferred location (whichever suits you).
  2. Using Google Chrome browser, navigate to chrome://extensions/ and enable "Developer mode" in the upper right corner.
  3. Click on the Load unpacked extension... button.
  4. Browse to the src directory of the unarchived folder and confirm.

If you have completed the above steps, the "welcome" page will open indicating successful installation of the extension.

Be sure to unsuspend all suspended tabs before removing any other version of the extension, or they will disappear forever!
