Why can't I uninstall older version of FFx from Windows 7
I have gone to Windows Control Panel and tried to uninstall older versions of FF, but nothing happens; no error message it just doesn't uninstall.

Let’s do a full clean re-install;
Save the file. Then Close Firefox.
Using your file browser, open the Programs Folder on your computer.
Windows: C:\Program Files C:\Program Files (x86)
Mac: Open the "Applications" folder. https://support.mozilla.org/en-US/kb/how-download-and-install-firefox-mac
Linux: Check your user manual. If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it. See Install Firefox on Linux; https://support.mozilla.org/en-US/kb/install-firefox-linux
If you downloaded and installed the binary package from the Firefox download page, simply remove the folder Firefox in your home directory. http://www.mozilla.org/firefox#desktop ++++++++++++++++++++++++++++ Do Not remove the profiles folder.
Look for, and rename any Mozilla or Firefox program folders by adding .old to them. Do not rename the Mozilla Thunderbird folder if there is one.
After rebooting the computer, run a registry scanner if you have one. Then run the installer. If all goes well, remove the OLD folders when you are done. +++++++++++++++++++++++++++ If there is a problem, start your Computer in safe mode and try again.

The Windows Control Panel "Uninstall a Program" uses a list from the Windows Registry. Sometimes for one reason or another that list is out-of-sync with reality. You can check what Firefoxes may be installed on these paths:
32-bit Firefox on a 64-bit Windows system:
C:\Program Files (x86)\Mozilla Firefox
Other combinations of Firefox and Windows:
C:\Program Files\Mozilla Firefox
There should not be more than one version installed at a time per location.
