I want to uninstall firefox 55 and keep firefox 60 - but can't!

Hi. New here.

I have both these installed, FF60 within Program Files and FF55 within Program Files (x86). These both appear on the apps list in Settings, also in installed programs in Control Panel. But choosing to uninstall 55 either way does nothing - the app remains. Tried CCleaner also doesn't work. But only one version of FF (the currently working FF60) shows in the Apps list from Start.

Also, when it comes to choosing default browsers I see two versions of Firefox but no version number. The only way to distinguish between is by the newer Firefox icon (a bigger fox).

Can anyone tell me how I could get rid of FF55 please?

It's simple if you know what you are doing. Open the Programs Folder that the unwanted Firefox is located.

Find the folder that Firefox is in and delete it. After, reboot the computer. Then run a registry scanner if you have one.

Ah thanks. But before I do this is the registry cleaner in CCleaner good enough?

Also I looked in the Program Files (x86) folder at the Mozilla folder and saw there was an uninstall folder, inside which was helper.exe (thinking that might run the uninstallation). But it didn't.

I think helper.exe is a Mozilla program. Not sure what it does.

If there are multiple versions of Firefox in "Control Panel > Programs" present then it is possible that you only see orphaned Firefox entries from older versions and that only the current release is really installed. This can happen if the Firefox updater didn't remove the entry of the previous version, but merely added an entry for the new version. If you uninstall such older versions that are actually no longer present then you will likely uninstall the current Firefox version and you will have to reinstall the current Firefox release.

If you are comfortable with the registry editor then you can remove Mozilla Firefox entries that no longer apply in the Uninstall registry key. "How to manually remove programs from the Add or Remove Programs tool":
