Change when tabs get auto-archived

Settings → Archive inactive tabs after: ...

Note that:

Archive a tab

To archive the current tab manually:

You can also archive any open tab by clicking [arrow down] icon next to an open tab.

Archive a window

There are several ways of doing this:

Archive a tab group

Click on the colored arrow

Restore a tab

In the Archived section, simply click on an item.

Can I choose where to restore it?

Right-click to show more options:

“In Original Tab” deserves an explanation. Say, the archived tab was 3rd in a particular window. When restoring, it will try to find that window and place the tab 3rd.

Restore a window (or a session)

Restore a tab group

Click on the colored arrow pointing up

Free up memory

Right-click a tab and select “Unload” context menu item:

Right-click → Unload

To unload all tabs in a window, right-click the vertical window bar:

Right-click → Unload

Tab group’s context menu has the same “Unload All” item.

Manipulate several tabs

Archive several selected tabs

  1. CtrlCommand-click them on the Chrome tab bar (or Shift-click to select a range)
  2. Click on “3 tabs” button
    (3 is the number of selected tabs in this example)

Archive everything but selected


Click “Archive Other” button in the extension popup.

Hold AltOption


Right-click while holding Alt to archive all tabs above in the selected.

Alt-Shift-Backspace⌥⇧Delete keyboard shortcut also archives tabs above the selected one.

Sync

Archived tabs are synced between Chrome browsers as long as “Sync is on”.

Where do you save my data?

Chrome stored this data on Google servers, Edge on Microsoft’s. The data is securely sent over HTTPS.

Can you read my data?

Absolutely not! Tab Cellar uses storage.sync API; extensions developers have no access to this data whatsoever.

How many tabs can I sync?

There’s no limit on how many archived tabs you can have on each machine. However, the sync storage can fit only ≈200 newest tabs.

Say, you archived 250 tabs in one day. The next day, you turn on another computer — it will sync the latest ≈200 tabs only.

How do I disable syncing?

Settings → Sync: Archived tabs

Will I lose all my previously synced data after disabling that?

No.

Cloud Backup

To set up your first cloud backup:

  1. Settings → Backup, Import or Export
  2. After signing up, you should see something like this:

You can access your backup as long as you have access to your email inbox.

If you set a password, your data is end-to-end encrypted. The password (or its hash) never leaves your device. However, If you forget your password, your backup is unrecoverable, even by us.

Backups are stored securely so that if the cloud storage is ever compromised, attackers cannot access user emails or decrypt any data. The data is encrypted using AES-256, an industry-standard encryption algorithm.

Export

To export all archived tabs to a *.tabs.json file

You can also export a window: right-click on the window bar → Export...

Import

Drag-drop your *.tabs.json file into the Archived section.

You can also open all of them by dropping into the open tabs section.

From OneTab

OneTab exports tabs as a list of URLs. You can copy/paste them to Tab Cellar (Settings → Backup, Import or Export).

Preserve page state when archiving

  1. Click on the gear icon to open settings

Keep the default blank tab page

  1. Open a blank tab
  2. Click on the gear icon at the top right
  3. Enable “Revert to default new tab page”

How do I access Tab Cellar then?

If you don’t have Tab Cellar on the new tab page, you can use Tab Cellar Mini:

Tab Cellar Mini runs in the extension Popup. It doesn’t include some features. Notably, you can’t restore archived windows, sessions, or tab groups from there. For that, you can open Tab Cellar in a new tab by clicking the icon in the bottom left of the popup:

Use another extension’s blank tab page

Install another extension after installing Tab Cellar.

This way Tab Cellar won’t override the blank tab page and will continue working otherwise. As of June 2024, this is the only solution I know.
