Ultimately I browse with many tabs opened at the same time doing investigations and research and found myself wanting to, somehow, save my current session and continue later or the next day.
My idea is, when I'm in Firefox and want to finish what I'm doing because I can't finish it at the moment my investigation or something else, some how, save my current session (opened tabs at the moment) clicking a button and wen its saved(remember current tabs opened) Firefox closes automatically, then later or the other day when I open Firefox again, it open the homepage and a notification from Firefox showing "restore last session?" and the same notification let me select yes or close notification which will cancel that.
I hope it can make a bit better Firefox.
