Tab Suspender Pro - Save Memory & Speed Up Chrome
Extension Actions
- Live on Store
The trusted tab suspender that saves memory and speeds up Chrome. Unlimited free. No limits. No tracking.
Save 4GB+ RAM instantly. Auto-suspend inactive tabs, free memory, speed up Chrome. The trusted open-source replacement for The Great Suspender same shortcuts, same workflow, zero data collection.
THE PROBLEM
Chrome wasn't built for 40+ tabs. Every open tab eats memory, drains battery, spins up fans, and slows your entire computer. Video calls stutter. Apps lag. Your laptop sounds like a jet engine. All because of background tabs you haven't looked at in hours.
THE SOLUTION
Tab Suspender Pro automatically hibernates inactive tabs and returns that memory to your system. Instantly. No manual work. No complicated setup. Install it and forget it — your browser just works better.
WHY TAB SUSPENDER PRO?
In January 2021, The Great Suspender was removed from Chrome Web Store after being flagged for malware. Millions of users lost their favorite extension overnight.
Tab Suspender Pro was built as the trustworthy replacement:
→ Same keyboard shortcuts you already know
→ Same workflow you relied on
→ Zero compromise on privacy
→ 100% open source — audit the code yourself
HOW IT WORKS
Set your timeout (5 minutes to 24 hours)
Inactive tabs get suspended automatically
Memory freed instantly
Click any suspended tab to restore in milliseconds
Your scroll position, form data, and session stay intact
That's it. No accounts. No configuration. No learning curve.
SMART PROTECTION
Tab Suspender Pro knows what NOT to suspend:
→ Tabs playing audio or video
→ Active video calls (Meet, Zoom, Teams)
→ Tabs with unsaved form data
→ Your current active tab
→ Pinned tabs (optional)
→ Whitelisted sites (Gmail, Docs, Calendar, etc.)
Your workflow stays protected. Background noise gets suspended.
KEYBOARD SHORTCUTS
Alt+S → Suspend current tab
Alt+Shift+S → Suspend all other tabs
Alt+R → Restore all suspended tabs
Alt+W → Whitelist current site
Power users rejoice. These are the same shortcuts from The Great Suspender.
