Session Manager lets you save sessions of your opened tabs and windows, and to quickly re-open them whenever you like.
With Session Manager you can quickly save your current browser state and reload it whenever necessary.
You can manage multiple sessions, rename or remove them from the session library.
Each session remembers the state of the browser at its creation time, i.e the opened tabs and windows.
Once a session is opened, the browser is restored to its state.
Some common usage:
Create sessions for daily routines: Pages you open on morning, noon and evening
Group pages of common interest such as News, Financial and Social Networks.
Save the pages found during a research session that you'd like to revisit later.
