Tab Memory Monitor

See how much memory each tab is using. Find the heavy ones and close them.

Short Description: See exactly how much memory each browser tab is using. Find the heavy ones and close or suspend them instantly. Detailed Description: Your browser is slowing down. Now you can see exactly why. Chrome is notorious for eating RAM. Tab Memory Monitor shows you a live breakdown of memory usage across all your open tabs - ranked, color-coded, and always up to date. What it does: - Opens to a live ranked list of all your tabs by memory usage - Color coded: 🟢 light, 🟡 moderate, 🔴 heavy - Shows each tab's share of your total JS heap (e.g. "23%") - Measures all tabs instantly when you open the extension — no waiting - Auto-refreshes every 5 seconds while open Take action: ~ Suspend a tab to free its memory completely - it reloads automatically next time you visit it ~ Close a tab directly from the list without switching to it ~ Sort by memory usage or name Lightweight and private: ^ No sign-up, no account, no cloud ^ Your data never leaves your browser ^ No analytics or tracking of any kind ^ Works offline A note on the numbers: Tab Memory Monitor measures JS heap memory per tab - the JavaScript memory each page is actively using. This is a subset of Chrome's full process memory (which includes GPU buffers, caches, and shared memory), so numbers will be lower than Chrome's built-in Task Manager. The rankings are accurate and reliable for identifying your heaviest tabs.
