Tabs Suspender von devvyyxyz

Tab Suspender automatically frees up memory by putting inactive tabs to sleep after a period of inactivity you choose. Instead of leaving dozens of tabs running in the background and consuming RAM, each tab gets replaced with a lightweight suspended page that preserves its title and URL. When you need the tab back, a single click restores it exactly where you left off.

How it works

• A content script detects your activity in each tab (clicks, scrolling, typing) and reports it to the background engine.
• The background script tracks how long each tab has been idle.
• Once a tab exceeds your chosen inactivity timeout, it gets suspended and its memory is released.
• Suspended tabs show a restore page with the original title, URL, and favicon. Click Restore Tab to reload it.

Key features

• Custom timeout: choose any inactivity period from 1 to 120 minutes.
• Adjustable check interval: control how often the engine scans for idle tabs.
• Pinned tab protection: pinned tabs are skipped by default, or you can include them.
• Form data safety: tabs with unsaved text in input fields are protected unless you opt in.
• URL whitelist: add patterns like *github.com* to permanently exempt certain sites.
• Quick popup: toggle the extension on or off, view live stats, or force-suspend all inactive tabs instantly.
• Full dashboard: open Settings to configure every option, manage your whitelist, and see suspension statistics at a glance.

Privacy

Tab Suspender does not collect, transmit, or share any data. All tab tracking and suspension state is stored locally in your browser. The extension requires the tabs, storage, alarms, management, and idle permissions to function, and nothing more.

Suggested pairing

Tab Suspender works well alongside tab management extensions like Focus Berry, which tracks your tab usage. Together they give you both visibility into your browsing habits and automatic memory management.
