Session Vault

Your browser restores your last session. This is for everything it doesn't keep. Session Vault writes a snapshot of your open tabs to a plain JSON file in your Downloads folder, on a schedule. If your tab manager loses your sessions — or disappears entirely — the files are still sitting there. This is not a tab manager. It is the recovery layer underneath the one you already use. WHAT IT DOES • Saves automatically every 30 minutes, every hour, or every 3 hours — your choice. • Snapshots go to files, never into extension storage. Uninstall this extension and the files remain. • Nothing is ever deleted. If nothing changed since the last snapshot, no new file is written. • Open a snapshot in any text editor and your URLs are right there. No import tool needed. • Restore rebuilds your windows and tabs from a file you pick. • Restores from other extensions' exports too — it looks for URLs, not for a format it recognizes. • A damaged file still gives up every URL it can, and the popup tells you the window layout was lost. A recovery tool that cannot recover is worthless. • Tells you if automatic backup ever stops. Failing silently is the exact problem this exists to prevent. PRIVACY • No account, no server, no sync. The extension makes no network requests at all. • Nothing leaves your machine. Snapshots are written only to your Downloads folder. • Four permissions, about 30 KB. Keep the tab manager you already trust. This one just writes the files.
