After several months of using I can say: Absolutely Vital. When you don't want to close a window (just in case you possibly would miss the tabs), save the window instead. No more gazillions of windows, and no tab is lost.

works

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。

It works perfectly. Even if it stops working in the future, I’m not the type of person to make unreasonable complaints about something free. I will continue to use it with gratitude.

dddddddddddddd

Это хорошо. Отлично. В общем радует. Все звёздочки мира ваши

It works and it works well
