Auto Suspend/Close Tabs Overview
What is Auto Suspend/Close Tabs?
Auto Suspend/Close Tabs automatically suspends or closes inactive tabs to free up memory, reduce CPU load, and extend battery life. This feature keeps your browsing experience faster, smoother, and more efficient.
How It Works
The extension monitors your tab usage and automatically manages inactive tabs based on your configured settings:
- Tab Suspension (Discard): Suspends inactive tabs while keeping them visible in your tab bar. Suspended tabs reload when clicked, preserving form content and scroll position.
- Tab Closing: Completely closes inactive tabs to maximize memory savings.
