ZeroRAM Suspender
ZeroRAM Suspender dramatically reduces your browser's memory usage by intelligently suspending unused tabs. Unlike traditional tab suspenders that use placeholder pages, ZeroRAM Suspender utilizes the browser's native tab discarding mechanism to achieve almost zero memory consumption for suspended tabs. When a tab hasn't been used for a while, the extension automatically suspends it using this native approach, freeing up memory while keeping the tab available for instant restoration when you need it. - **Near-Zero Memory Usage**: Uses native browser discarding to achieve almost zero memory consumption for suspended tabs - **Automatic Tab Suspension**: Tabs are automatically suspended after being idle for a set time (default: 30 minutes) - **Memory Optimization**: Choose between native browser discarding or lightweight placeholder pages - **Whitelist Support**: Protect important websites from being suspended - **Manual Controls**: Suspend or unsuspend tabs manually when needed - **Tab Migration**: Seamlessly migrate suspended tabs from other tab suspension extensions (like The Marvellous Suspender) - **Simple Interface**: Easy-to-use popup and settings page - **Privacy Focused**: All processing happens locally - no data is sent to external servers
