When I install a later version of Firefox then what I have installed on my PC, It just leaves that version and installs the newer version. How can I uninstall the earlier version, when installing a later version?

Are all those version really installed in separate Firefox program folders or are there merely orphaned entries in the Windows Registry that weren't removed by the updater?

Are they all the same versions ()32 bit or 64 bit?

  • (64-bit Firefox) "C:\Program Files\Mozilla Firefox\"
  • (32-bit Firefox) "C:\Program Files (x86)\Mozilla Firefox\"
