About this extension
Keep your browser fast and responsive with FFSleep.

FFSleep allows you to "discard" inactive tabs, freeing up valuable system memory (RAM) without closing them. Sleeping tabs stay in your tab bar and reload automatically only when you click them again. It’s the perfect solution for users who keep many tabs open.

Key Features: - Manual Sleep: Put any background tab to sleep with a simple moon icon. - Sleep All: Instantly discard all inactive tabs to boost performance. - Tab Search: Quickly find and manage specific tabs using the built-in search bar. - Modern UI: A beautiful, dark-themed interface designed for ease of use. - Lightweight: No background battery drain; it works only when you open the popup.

Let your tabs rest and keep Firefox running smoothly with FFSleep.
