how to open main dialogto save tabs?i dont see any options,please help me

*edit* thanks for update, i can now see how it work and that is great time saver,menu just dont show in orange button in firefox

This review is for a previous version of the add-on (0.9). 

I just realized the maximum compatibility was set to version 10.*; this might have prevented the menu item from showing up. I have now updated it to 19.* to be in line with the latest official Firefox release. You may need to reinstall from the add-on site. Sorry about that!

*Edit* My original reply seems to have gone away. In it, I said that there should be a menu item called 'Tab Set Saver' in the Tools menu, and that it might be necessary to press Alt or F10 to make the menu bar visible.
