Unload All Tabs 제작자: Quazarex

This extension adds a simple command to unload (discard) all open tabs except the currently active one and any pinned tabs. Discarded tabs remain in your tab bar, but their memory usage is freed until you click them again.

By default, the keyboard shortcut is Ctrl+Shift+U. You can change this in Add-ons → Manage Extension Shortcuts.
