Session Boss: Save and Restore Browser Sessions

'Session Boss' is a powerful Firefox add-on that autonomously captures and saves your browsing sessions, enabling you to restore your tabs and windows at a later time. It functions by periodically saving sessions and detecting URL changes. Key features include the ability to save and restore tab containers, lazy tab loading, session grouping, and the capacity to search and filter sessions, windows, and tabs. It prioritizes your privacy by defaulting to exclude private browsing windows from session saves.

It pisses me off.

Doesn't work at all. This extension is useless and can't save any session. Doesn't support private windows and GUI is buggy. I don't get it what you have updated there 3 months ago, but it simply doesn't work.
