das beste Addon zu Sessionverwaltung in Firefox und Opera Web Browser!! Benutze es seit mehreren Jahren in Firefox und nun auch in Opera - absolut zuverlässig und unglaublich simpel zu bedienen.

完全に動作します。仮に将来動かなくなっても無料の物に理不尽なクレーム付けるほど人間腐ってません。今後とも感謝しながら使わせていただきます。

Where the hell are all my tabs!!!??
The settings have ALL my windows and tabs to automatically save and restore... I am missing more than half my windows and hundreds of tabs!!!
