Session Manager addon

What do we need while surfing the web? Convenience.
What do we use to achieve convenience? We use lots of functional things provided by the browser, but one of the most important of them is the Bookmark feature. It gives user fast access to the web-pages user had an experience with earlier.

In my work I often use bookmarks, but not always one bookmark can reflect the entire "workspace" I need to establish. For that purpose the Firefox browser has a possibility to open all the bookmarks in the particular folder at once. That really works, but there are some problems:

• All the bookmarks will be opened in the same window, that isn't always good, especially if the folder contains more than 5-6 bookmarks which don't fit into the tab-bar. It would be good to open those bookmarks in several windows.
• All the bookmark-pages will be loaded from the "zero" point, that isn't always good too, because sometimes a web-page needs some session cookies to work properly.
  

To solve these two problems we can use so-called Session Manager add-on - the add-on that allows user to store the current state of the browser, and to recover it any time he/she wants.

After that add-on is installed into your Firefox, please don't forget to customize your tool-bar in order to show the session-manager's button.
