Hello, Using windows 10. Firefox wont open but get a box telling me old Firefox is running needs to be closed. Have shut it down but still nothing happens. I think I may have backed up my bookmarks on my PC but not sure where they are? Also tied entering and this dispalys C:\Users\Chris>AppData\Roaming\Mozilla\Firefox\Profiles\ 'AppData\Roaming\Mozilla\Firefox\Profiles\' is not recognized as an internal or external command, operable program or batch file. Help please to restore Firefox and hopefully not loose my bookmarks?

Thank you

Only the Default I created today so that Firefox would open

Root Directory C:\Users\Ed\AppData\Roaming\Mozilla\Firefox\Profiles\5neluwfr.Default User Local Directory C:\Users\Ed\AppData\Local\Mozilla\Firefox\Profiles\5neluwfr.Default Use

Which profile folder? Local or Roaming?
