Session Manager Chrome Extension — Automatic Tab Snapshots
Automatic tab snapshots every 5 minutes, on by default. The 50 most recent are kept in a ring buffer, covering about four hours of tab history.
Updated
Time Travel is a passive safety net that automatically snapshots your entire tab state every 5 minutes. You can rewind to any of the last 50 snapshots and restore it into this window.
How It Works
Every 5 minutes, SuperchargeNavigation captures a snapshot of your open tabs, groups, and pinned tabs. These snapshots are stored in a ring buffer: once 50 snapshots exist, each new one replaces the oldest. The result is a rolling window of roughly four hours of tab history: 50 snapshots at 5-minute intervals, and because unchanged states are skipped, the retained history can span much longer.
When you open the Time Travel panel, snapshots are listed with timestamps. Select any snapshot, and it restores into this window, replacing the tabs open here. Your current tabs are saved first as a Workspace, and a short Undo puts them back if you change your mind.

When to Use This
After a crash: Chrome or your system crashed and you lost your tabs. Open Time Travel, find the last snapshot before the crash, and restore it.
Accidental closure: You closed a window or tab group by mistake and Ctrl+Shift+T isn’t recovering everything you need. Time Travel has a complete snapshot of your session state.
“What was I looking at earlier?”: You were deep in a research session this morning and want to return to that exact set of tabs without rebuilding it from scratch. Find the snapshot from that time and restore.
Complement to intentional workspaces: Workspaces are what you save on purpose. Time Travel is the automatic backup behind every session — you get both layers of protection with no extra effort.
Privacy
Snapshots contain tab URLs and group metadata. They are stored entirely in Chrome’s local storage on your device and are never transmitted to any external service.
