Tab Memory Manager Firefox

Tab Memory Manager

See how much RAM each tab uses, then hibernate, close, or group idle tabs in one click. 100% private — nothing leaves your device.

Features & Capabilities

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.

Is Tab Memory Manager Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Tab Memory Manager requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details
  • Critical Grants access to browser tabs, which can be used to track user browsing habits and history, presenting a privacy concern.
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
