When I recently downloaded FF4, I was asked if I'd like to have FF automatically open the same tabs as were set in my IE. Great! Worked perfectly until I set those tabs as App Tabs. Now both the App Tabs and the original IE set of tabs open whenever I open FF -- essentially each tab loads twice -- as app tab and large tab. How can I delete tabs from the list of "auto-open" tabs? In addition, for some reason, every time I try to set my home page, it's not working -- I keep getting the same home page regardless of how many times I have tried to set a new one.
