How It Works

SleepyTabs monitors your open tabs and puts tabs to sleep that have been inactive for your specified time period. When a tab is sleeping, its contents are unloaded from memory but its visual representation remains in your browser. This significantly reduces memory usage while keeping your tabs organized.

Installation

Firefox

Chrome

1. Download the extension from your browser's extension store
2. Click "Add to Browser"
3. Configure your preferences in the extension popup

Usage

Basic Controls

• Put Tab to Sleep: Sleeps the current tab

• Put pinned tabs to sleep: When enabled, pinned tabs will also sleep
• Auto-wake tabs when clicked: When enabled, sleeping tabs automatically wake up when clicked

• Tabs requesting attention

Whitelist

Add domains or URLs to the whitelist to prevent specific sites from being put to sleep.
