TabSavior од Andrei Solomon

TabSavior saves every open tab, from every window, into your browser's own bookmarks — organized into folders you control the naming pattern for.

One click on "Save all windows" creates a bookmark folder per window, named however you like using a simple template like TabSavior/{YYYY-MM-DD}/{WindowTitle}. Restore any saved session later as a new window or appended to your current one.

Everything is local-first: your tabs, titles, and URLs are never sent anywhere. There's no account, no server, and no telemetry — just your browser's native bookmarks, which you can always view, move, or delete yourself, with or without TabSavior installed.

Features:
• Save all (or just selected) open windows in one click
• Customizable folder-path template with live preview
• Restore a session as a new window or appended to your current one
• Import sessions from Session Buddy exports or TabSavior's own exports
• Resilient to interruptions — a save that gets cut off resumes where it left off instead of duplicating or losing bookmarks
