Auto Tab Discard for Chrome, Firefox, Edge, and Opera automatically discard inactive tabs to free up tab memory usage and prevent background scripts from using your browser's computational power when the tab is inactive.

Auto Tab Discard uses the native method to discard tabs. In this method, the discarded tabs will not use any memory and can be restored to the previous state while preserving page state (like scroll position, for instance).

Auto Tab Discard Features:

Discards inactive tabs after a specified time period
Discards all tabs or tabs in the current window per user action
Supports white-listing for hostnames that should not go to the discarded state
Supports conditional options to prevent tab discarding (pinned tab, media playing, and power connection)
