About this extension
This extension improves browser performance by automatically suspending inactive tabs, reducing memory and CPU usage. It offers flexibility with customizable settings and user-defined exceptions.

Features:

Tab Suspension
  • Automatic Suspension: Inactive tabs are automatically suspended after a user-defined delay (default: 1 minute). Suspended tabs are replaced with a custom suspension page that stores the original URL and title.
  • Suspend Current Tab: Instantly suspend the currently active tab.
  • Suspend All Other Tabs: Suspend all tabs except the current one.
  • Suspension Timer Configuration: Users can set a custom delay in hours and minutes for when tabs should be discarded.

Toggle Options
  • Enable "Tab Suspender Mini": Lightweight mode for basic suspension functionality.
  • Enable Screenshots: Toggle screenshot capturing on or off during suspension.

Exception Handling
  • Domain Exceptions: Maintain a list of domains that will not be suspended. The extension checks URLs against this list before suspending tabs.
  • Easy Domain Management: Add and manage exception domains directly from the extension popup.

Special Cases
  • Audio Playback Protection: Tabs playing audio will not be suspended to avoid interruptions.
  • Browser-Specific URLs: Ignores certain internal browser URLs (e.g., about:, chrome:, moz-extension:) to ensure smooth operation.
