Isisombululo esikhethiwe

Sometimes, program uninstallation entries are not properly removed¹. Don't click them, or you'll end up uninstalling the current version of Firefox.

You can manually remove such entries from the registry. To launch the registry editor, click the Windows logo orb on the taskbar, then in the search box type regedit.exe and press Enter. Exercise caution when using the registry editor; you may want to back up the parent key first by right-clicking it and choosing Export.
For example, the uninstallation entry for the current version, English (US) locale can be found in the following locations:

  • 32-bit Windows:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Mozilla Firefox 27.0.1 (x86 en-US)
  • 64-bit Windows:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\Mozilla Firefox 27.0.1 (x86 en-US)
