SmartTab Unloader - Free RAM & Memory Saver by Undist

SmartTab Unloader is a lightweight and powerful Firefox extension designed to reduce browser memory usage and keep your system running smoothly. It automatically unloads (discards) inactive tabs based on your custom idle timers, freeing up valuable RAM without closing your tabs.

• Automatic Tab Unloading: Automatically suspends inactive tabs after a set period to reclaim system memory (RAM).
• Customizable Idle Timer: Set your preferred inactivity duration anywhere.
• Smart Tab Protection:
• Audio Protection: Prevents tabs playing music or video audio from being unloaded.
• Pinned Tab Protection: Keeps your pinned tabs active at all times.
• Domain & Path Whitelisting: Exclude specific websites or subpaths so they are never automatically unloaded.
• One-Click Instant Unload: Instantly unload all other inactive tabs with a single button in the popup menu.
• Right-Click Tab Context Menu: Easily add or remove current tabs from your Whitelist via the context menu.
• Live Memory Stats: Displays an estimated count of sleeping tabs and total RAM saved directly in the popup interface.
• Dark & Light Themes: Modern, clean, and responsive UI with built-in theme toggling to match your browser setup.
