Reproducible: Always Steps to Reproduce: 1. Open several browser tabs 2. Open the Download window (Ctrl-J or Tools -> Downloads) 3. Close the main window, but leaving the Download window open 4. Open Firefox (i.e. launch it from start menu, desktop shortcut, whatever) Actual Results: The re-opened main frame contains only my home page Expected Results: I should get the tabs I had open, as that's what happens when I close the browser and re-launch without the Downloads window around to confuse things. Either: - When re-opening Firefox, detect that it does not already have the first window open, and therefore load my session from the store containing the tab information. Or (perhaps, but not a good solution): - When closing the last window, also close the download window
