About this extension
Smart Tab Hibernator keeps Firefox fast and minimizes RAM usage by automatically putting inactive tabs to sleep. This lightweight browser memory-saver safely discards background pages, frees up device hardware resources, and secures your offline data privacy.

Tired of a sluggish browser? When you keep multiple tabs open, hidden background scripts, heavy tracking frameworks, and stale web app processes quietly drain your system’s memory (RAM), killing battery life and CPU performance. Smart Tab Hibernator resolves this bottleneck using automated, system-level tab management routines to unload background tabs until you actually need them.

Comprehensive Optimization Features:
• Automated Fixed Timer Loop: Take back control over resource allocation. Choose a custom countdown interval (e.g., 15 minutes) to seamlessly trigger an background memory sweep. Idle tabs are put into a deep freeze sleep, releasing active system constraints instantly.

• Smart Tab Limit Threshold: Perfect for heavy tab-surfers. Set a strict maximum tab count ceiling. The moment an added page pushes you past your custom workflow threshold, the extension auto-hibernates your oldest, untouched background sessions to keep your machine responsive.

• On-Demand Manual Memory Purge: Open the dashboard at any time to run a targeted cleanup sequence. This flushes temporary application caching layers, dead background storage variables, and service worker processes immediately with a single click.

• Intelligent Exclusion Guards: Your primary workflows remain safe. The engine strictly avoids affecting pinned utility tabs, native browser system states (about: configurations), and tabs actively streaming or rendering background audio/video media. Your background background music, playlists, and video calls will never be disrupted.

Optimized for Performance, Security, and Freedom:
Built strictly under modern WebExtension Manifest V3 guidelines, this extension requires no external server calls, remote data sync connections, or heavy script injections.

• 100% Client-Side Privacy: Operates entirely offline inside a local sandbox container. It does not track, read, record, or transmit browsing habits, history logs, or personal metrics.

• Ultra-Lightweight Core Layout: Written in clean, unminified JavaScript to ensure a near-zero physical memory footprint.

Reclaim your computer's speed, maximize device processing efficiency, and experience smooth, uninhibited browsing performance with Smart Tab Hibernator.
