Tab Backup by LGS

Tab Backup keeps your tabs safe and your windows tidy.

<b>Stash tabs</b>
• Stash a whole window (Alt+Shift+S), one tab, or the selected tabs into named groups in the sidebar (Alt+Shift+B).
• Firefox tab groups are kept: each one is stashed as its own group and comes back as a tab group, with the same name and colour, when you restore it.
• Groups are stored as bookmark folders (Other Bookmarks › Tab Backup), so they also sync with Firefox Sync.
• Restore single tabs or whole groups; restored tabs load only when you select them.
• Rename, search, drag and drop, and undo deletions from "Recently deleted".

<b>Back up everything</b>
• Snapshots of every window (pinned tabs, tab groups and containers) plus your whole stash, as readable JSON.
• Automatic on a schedule (15 minutes to daily), skipped when nothing changed, and shortly after stash edits.
• Keeps the newest N backups per destination.
• Destinations: a folder inside Downloads (no setup), any local folder (with a small optional helper program), Google Drive, Microsoft OneDrive and Dropbox.

<b>Restore</b>
• Browse backups from any destination or import a backup file, preview it, then reopen the windows or stash groups you pick.

<b>Cloud destinations</b>
Cloud backups currently need your own free app registration (client ID) with Google, Microsoft or Dropbox. The settings page shows the redirect URL to use, and step-by-step instructions are linked from there. Access is limited to the app's own folder.

<b>Privacy</b>
Tab Backup has no server and sends no telemetry. Backups go only to the destinations you enable. Uploading to a cloud service shares your tab URLs and stash with that service and is only done after you allow it in Firefox's data consent prompt.
