Tab Memory Manager

Tab Memory Manager shows you exactly which tabs are the culprits — then frees the memory in one click. No accounts, no servers, no tracking.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT IT DOES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

📊 See memory per tab A clear estimate of how much memory every open tab is using, with a live total right on the toolbar icon. Sort by memory, idle time, domain, or "most suggested."

💤 Hibernate or close idle tabs Free up RAM without losing your place. Hibernating keeps the tab in your strip and reloads it when you click — far safer than closing. See exactly how much you'll save before you act.

✨ Smart cleanup suggestions The extension surfaces your biggest, stalest tabs — the ones safe to clear — and frees them in one tap. It never touches the tab you're using, pinned tabs, tabs playing audio, or domains you've whitelisted.

🗂️ Group tabs by domain Turn a chaotic window into tidy, color-coded groups by website, instantly. One click to group, one to undo.

↩️ Undo safety net Closed something by mistake? Every cleanup is saved to a "Recently cleaned" list so you can restore tabs with one click.

🌙 Built for everyone Fast, lightweight, no frameworks. Automatic dark mode. A clean, minimal interface that opens in under 100 ms.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PRIVATE BY DESIGN ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Your tabs are your business. Tab Memory Manager runs entirely on your device: • No account or sign-in • No servers, no analytics, no tracking • Your tab data and stats never leave your browser

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ HOW THE MEMORY NUMBERS WORK ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Firefox doesn't expose exact per-tab memory to extensions, so Tab Memory Manager shows calibrated estimates (clearly labeled "est.").

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PERFECT IF YOU ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

• Keep dozens (or hundreds) of tabs open • Notice Firefox slowing down or your fan spinning up • Work on a laptop with limited RAM • Want a tab suspender that's honest, private, and simple

Install it free, pin it to your toolbar, and reclaim your memory.
