I couldn't force this to open in a firefox window as a tab. It wouldn't close when I clicked the red X and I also couldn't modify the options I chose for it when I created the tab.
Plus there was the annoying fact that it simply ignored all of my extensions. It should respect my choices like Ad Block Plus and Auto-Hide Statusbar. I sincerely hope it'll also respect Jetpacks by the time it comes out of Beta.
