What The Marvellous Suspender is

Inactive tabs are replaced with a lightweight hibernation page shown as a screenshot, blurred, or text-only, with session recovery after crashes and a power mode that suspends tabs on low battery. It is based on The Great Suspender, which Google removed from the store in 2021 after an ownership change; this project is maintained separately.

Feature coverage

  • Automatic suspension after a set idle time
  • Screenshot, blurred, or text-only placeholders

What stands out

  • Open source under GPL-2.0
  • Developer declares no data collection
  • Updated in September 2026

Tradeoffs to know

  • Removing it can lose suspended tabs
  • Overlaps with Chrome's built-in Memory Saver
  • Modest rating sample

Permissions and privacy

Page access

Suspending a tab means reading its URL and title and swapping it for the extension's placeholder page, which takes tab access; screenshot placeholders also capture the visible page. The optional Google Drive backup requests only the drive.file scope, which limits it to files the extension creates. Unsuspend all tabs before disabling or removing it.

Data notes

The listing declares no data collection, and the developer's privacy policy says nothing is sent to Marvellous Codeworks servers. Tab URLs, session layout, and history stay in local browser storage. If you enable Google Drive backup, data goes directly from your browser to your own Drive, and the extension keeps at most 10 automatic backups.

Pricing

Free and open source. Pricing and plan limits change more often than store metadata, so use the linked developer page as the final check before subscribing.
