The link above is the Browser-Plugins list for Fire-Fox left after running Ccleaner I can understand most of them but the Windows.old locations baffle me as they are no longer on my drives as I deleted windows.old through storage settings after 10 days. Any idea how to get CCleaner to delete them (( can disable the old ones

I would create a new FF profile and start from scratch, if that clears out those weird extensions then you can always copy your key4.db, cookies.sqlite, places.sqlite, bookmark file etc to the new profile folder.
