Chrome tabs lost after an update — how to get them back

Why an update restart loses your tabs

Chrome's "Continue where you left off" setting and its on-startup session restore read from a session file the browser writes as you work. An automatic update relaunches Chrome, and that hand-off is where things break: if the session file was mid-write, if the update reset the startup setting to "Open the New Tab page", or if the relaunch is treated as a fresh start rather than a resume, the previous windows are not reopened. Even when some tabs do return, Chrome restores them as a flat set — the chrome.tabGroups structure that held your group names, colors, and collapsed state is not reliably rebuilt, so a session that did come back often comes back ungrouped.

Native recovery attempts and where they fall short

Before installing anything, it is worth trying what Chrome already offers — but each native path has a hard limit:

• Reopen the relaunch prompt. If Chrome shows a "Restore pages?" bar after the update, click it immediately; it disappears once you open other tabs, and it only targets the single most recent session.
• History > Recently closed. Lists individual tabs and windows from recent sessions, but the list is short, and reopening a window does not restore its tab groups.
• Ctrl+Shift+T. Reopens closed tabs one at a time from recent history and stops once that history runs out. It is built for a tab you just closed, not a whole session — covered in detail in the recover-closed-tabs guide linked below.
• Settings > On startup. Confirm it is set to "Continue where you left off" so the next relaunch at least attempts a resume; this protects future restarts, not the one that already happened.

All of these depend on Chrome's own session state, which is exactly what an update restart can clear. None of them rebuilds tab groups.

The durable fix: an auto-snapshot taken before the update

The reliable way to survive an update is to have a copy of the session that does not live inside Chrome's volatile session file. Tabwell, added from the Chrome Web Store, writes an auto-snapshot when Chrome exits, so the relaunch that an update triggers is treated as an exit-and-restart: the pre-update session is already on disk in local IndexedDB. The next launch offers to restore whatever was open, and a restore recreates each window, the tab order inside it, and every tab group with its original name, color, and collapsed state read back through chrome.tabGroups. Because the snapshot is local to your device, it survives the update that wiped Chrome's own session and does not depend on any account or network call. The Free tier runs this auto-snapshot every 60 minutes; Pro tightens it to every 5 minutes for sessions that change fast. For the step-by-step restore flow, see the restore guide linked below.

Be honest: recovery needs a snapshot that already existed

Tabwell can only bring back a session it had already captured. If an update lost your tabs before Tabwell was installed, there is no snapshot to restore from, and the native paths above are the only options. That is why the value here is protective: install before the next update so the auto-snapshot-on-exit safety net is in place when Chrome relaunches without warning. Once it is running, the latest 5 snapshots on the Free tier are enough to roll a surprise update back to the last save, and a manual save before you click "Relaunch" captures the session at that exact moment.
