About this extension

Free up RAM by automatically suspending inactive tabs.

Read the publisher’s full description

Slumber automatically suspends inactive tabs to free up RAM and keep Chrome running fast, especially if you keep dozens of tabs open at once. How it works: When a tab hasn't been viewed for a set amount of time, Slumber puts it to sleep. The tab stays in your browser but uses virtually no memory. Click it any time to instantly wake it back up. Features - Auto-suspend inactive tabs after 5, 10, 20, 30, or 60 minutes - Suspend all tabs instantly with one click - Keyboard shortcut (Ctrl+Shift+S / Cmd+Shift+S) to suspend the current tab - Whitelist: keep important tabs like Gmail or Spotify always awake - See exactly how many tabs are suspended and how much RAM is saved - Clean suspended page shows the original tab title and URL Privacy Everything runs locally on your device. No browsing data, URLs, or tab content is ever sent anywhere. No account required. Why Slumber? The most popular tab suspender extensions were abandoned or caught injecting malware. Slumber is actively maintained, fully open about what it does, and built on Chrome's latest Manifest V3 platform.
