Session Manager & Tab Saver — PureSession od Antoni0

PureSession keeps all your tabs and sessions in one fast side panel — and never sends them anywhere.

FREE
• All open windows and tabs in the side panel: click to switch, drag to reorder, close in one tap
• Sleep tabs to free memory — single tabs, a window or everything (the counter shows an estimate of memory freed)
• Remove duplicate tabs across all windows — pinned and active tabs are kept, and there is Undo
• Save the current window or all windows as a named session; restore it in a new window or add it to the current one
• Big sessions open asleep, so restoring 100 tabs doesn't freeze your computer
• Automatic backups every few minutes, when a window closes and before every restart — restore the newest one any time
• Last session before restart: if the browser crashes or closes, your previous tabs are one click away
• Lock one session with a password
• One-click migration from Session Buddy, Toby and OneTab — plus bookmark files (.html) and plain lists of links
• Full JSON backup and restore of everything

PRO — one-time payment, no subscription
• Full backup history (time machine): restore any of your last 50 backups, not only the newest, and choose how often they run
• Unlimited password-locked sessions: AES-256-GCM, key derived on your device (PBKDF2, 600,000 iterations)
• Deep search across every saved session and backup — words, site:, dates, regular expressions
• Export to Markdown checklists for Obsidian and Notion, or to CSV

ABOUT PERMISSIONS — WHY THE BROWSER MENTIONS "BROWSING HISTORY"
To list your tabs, PureSession needs the "tabs" permission, which lets it read the titles and addresses of open tabs. Browsers describe that as reading your browsing history. That is all it reads: PureSession has no content scripts, so it cannot see what is on the pages you visit, and it has no access to any website. Titles and addresses are stored only in your browser.

PRIVACY
No account, no analytics, no tracking. The only network request PureSession can make is a license check with Gumroad when you activate a Pro key.

Shortcut: Alt+Shift+S.
