The short answer, spelled out
If you close Chrome and reopen it, a tab group might come back. Two things determine the outcome: whether the group was saved using Chrome's built-in save feature, and whether your Chrome is set to restore the previous session on launch. Get both right and your groups usually come back. Get either wrong and they disappear without warning.
Saved vs unsaved tab groups
Chrome introduced saved tab groups specifically to fix this reliability problem. An unsaved group is just a colored pill that lives in the current window. Close the window without Chrome restoring the session and it is gone. A saved group has a small bookmark-style indicator and persists across Chrome launches — you can reopen it in any window. If you turn on "Show tab groups in bookmarks bar" under Settings → Appearance, saved groups show up there too; otherwise they live under the three-dot menu → Tab groups.
To save a group: right-click the colored pill and toggle Save group. That's the whole thing.
Quick sanity check
Right-click every tab group you care about and confirm "Save group" is on. Any group without that toggle active can vanish on the next Chrome close.
What happens on a normal quit
Saved groups survive regardless of your startup setting. Unsaved groups depend entirely on whether Chrome is configured to restore the previous session. If you have "Continue where you left off" set at chrome://settings/onStartup, unsaved groups usually come back on next launch with their colors and names intact. If your startup setting opens a new tab page instead, the previous session is never restored and the groups are gone.
What happens after a crash or forced update
This is where most people lose work. A crash generally triggers Chrome's "Restore pages?" prompt on next launch — click it and unsaved groups usually come back, dismiss it and they do not. A forced update that relaunches Chrome in the background can skip that prompt entirely, which means unsaved groups may just be gone. If Chrome was killed by the OS for memory pressure (rather than a proper crash), the restore path is even less reliable.
A profile reset or "Clear browsing data" action that includes Tabs wipes everything, saved groups included. That one requires a deliberate action, but it happens.

How sync changes the picture
Saved tab groups sync through your Google account when Chrome Sync is on and the Saved tab groups toggle is enabled. Find it at Settings → You and Google → Sync → Manage what you sync. It is a separate toggle from "Open tabs" sync — enabling one does not enable the other. Open a saved group on your laptop and it shows up on your desktop Chrome signed into the same account. As of Chrome 133 (early 2025), both Android and iOS Chrome support creating, viewing, and syncing saved tab groups. A few details differ from desktop — no tab group pinning on Android, no drag-and-drop on iPhone — but the core loop works on both.
Sign out of Chrome and saved groups stay on the local device but stop appearing elsewhere. Switch Google accounts and the groups follow the account, not the hardware.
Sync is not a backup
It mirrors the current state across devices. If you delete a saved group on one device, the delete syncs too. This is exactly how people have accidentally wiped their groups from every machine at once.
How to make groups actually stick
Four steps, in order of how much they protect you:
- Set "Continue where you left off" at
chrome://settings/onStartup. This covers the normal-quit case for unsaved groups. - Right-click every group you care about and toggle "Save group". This is the single most effective thing you can do.
- Keep Chrome Sync on with the "Saved tab groups" toggle enabled so your groups exist on more than one device.
- Take an independent snapshot of any group you cannot afford to lose. This is the one Chrome does not handle — you need an outside copy stored somewhere other than Chrome's own storage.
That fourth step is where a snapshot tool earns its keep. A point-in-time copy of your full layout (group names, colors, order, every tab) lives outside Chrome's storage, so a profile wipe cannot touch it.
Where TabGroup Vault fits
TabGroup Vault is that backup layer. One click saves a full snapshot of your tab groups including names, colors, and pinned tabs. The Pro tier adds Google Drive backup so snapshots survive reinstalls and profile resets. Free tier covers 5 snapshots. Full guide to saving tab groups in Chrome →
A few edge cases
Incognito tab groups never save — incognito is intentionally ephemeral, so nothing persists after the window closes. Guest profiles work the same way. If your company manages your Chrome, enterprise policies may wipe session data on close regardless of your personal settings; worth asking IT. Chrome on iOS is WebKit-based, and tab group feature parity with desktop has been catching up since Chrome 133 but is not identical.
The short version
Saved tab groups are much more reliable than the old model Chrome shipped in 2020. For day-to-day use, "Continue where you left off" plus the Save group toggle gets you through 95% of scenarios fine. The remaining 5% — profile resets, corrupted storage, enterprise wipes, a dead hard drive — is where an outside snapshot tool is the difference between a minor annoyance and losing a week of context.
