Tab Cemetery od SolarSpark99

Tab Cemetery is a sleek, minimalist Firefox extension that automatically sweeps and closes inactive tabs to save memory and reduce visual clutter.
Are you constantly drowning in dozens of leftover tabs? The Tab Cemetery "Reaper" acts as an automated housekeeper. It quietly runs in the background and closes tabs that you haven't touched in a while—keeping your browser fast and your workspace clean.
Key Features:
• The Reaper (Auto-Cleanup): Automatically purges tabs that have been inactive longer than your customized threshold.
• Smart Guardrails: Built-in intelligence ensures it NEVER closes active tabs, pinned tabs, or any tabs actively playing audio (like Spotify or YouTube).
• Customizable Inactivity Thresholds: Choose exactly when a tab is considered "dead" (options ranging from 30 minutes to 24 hours).
• Buried Tab Counter: A fun visual tracker built into the gorgeous dark-mode popup that counts the total number of tabs the extension has successfully buried for you.
Technical Details:
Tab Cemetery is built to be extremely lightweight and natively supports Firefox's background scripting architecture.
