About Smart Memory Saver
Keep your tabs. Use less memory. Smart Memory Saver automatically puts inactive
tabs to sleep so Chrome stays responsive, no matter how many you keep open.
Tabs you haven't touched for 30 minutes go quiet in the background. They stay
right where you left them in your tab bar — same position, same title — ready to
load again the moment you click. Nothing is closed and nothing is bookmarked.
You don't lose your place in your own browsing.
WHAT IT DOES
• Sleeps inactive tabs automatically — uses Chrome's built-in tab discarding to
free a tab's memory while keeping it visible and one click away
• Never sleeps what you're using — the tab you're looking at is always left
alone, and by default so are pinned tabs, tabs playing audio, and video call
sites like Google Meet, Zoom, Teams and Webex
• Your own never-sleep list — add any site that should always stay loaded
• Sleep on demand — Alt+Shift+S sleeps every idle tab, Alt+Shift+Z sleeps the
one you're on. Right-click any page for the same actions
• Choose your intensity — Manual (nothing sleeps unless you ask), Balanced
(the default), or Aggressive (half the idle time, for very large windows).
Set the idle timer anywhere from 5 minutes to 4 hours
• A dashboard that adds up — see at a glance how many tabs are in use, idle,
asleep, and kept awake, plus an estimate of the memory sleeping tabs are
freeing right now
HOW IT WORKS
1. Install and click the Smart Memory Saver icon to open the dashboard
2. Pick a mode — Balanced is the default and suits most people
3. Carry on browsing. Idle tabs are put to sleep in the background
4. Click a sleeping tab whenever you want it back — it reloads and you carry on
5. Open the popup any time to see where you stand or adjust what's protected
WHAT SLEEPING ACTUALLY DOES
A sleeping tab is discarded by Chrome and reloaded when you return to it, so
it behaves like a fresh page load: anything you had typed but not saved is not
preserved. That's exactly why the extension never sleeps the tab you're on, and
why pinned tabs, audio, video calls and your own listed sites are protected by
default. If a page matters, put it on the list and it will never be touched.
ABOUT THE MEMORY FIGURE
Chrome does not report per-tab memory to extensions, so the "freed right now"
number is an estimate of roughly 80 MB per sleeping tab. It is labelled as an
estimate everywhere it appears. The tab counts are exact.
PRIVACY
Everything stays on your device. Smart Memory Saver makes no network requests of
any kind — no analytics, no telemetry, no remote fonts. The extension's manifest
sets connect-src 'none', so outbound connections are blocked by the browser
itself rather than merely promised. There is no account and nothing to sign up
for. Settings and counters are stored locally and are never synced or uploaded.
Free, no ads, no upsell.
