Tab Suspender Mini by Mawn

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.

• 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.

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

• 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.

• 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.

Warning!!

Before updating the extension, unsuspend all tabs first (Popup → Unsuspend Others, or click each suspended tab to restore it).

Suspended tab URLs point to the old extension ID, so after an update they may fail to restore on click.
