I'm use to have many Firefox windows open at the same time (usually 5-8), each one with dozen of tabs and it's difficult remember in which window a certain tab is open. So I think it would be useful hava a command to list all windows and tab open and be able to save this list in another program (text, spreadsheet, presentation or whatever. I searched in Firefox help, but find nothing: is my fault (so, please, suggest ho to do it) or a lack of feature? Many thanks
