Despite following all instructions to make Firefox my preferred Browser in Win10, the system persistently tells me that Firefox is NOT my preferred Browser, and I cannot seem to do anything about it. Thanks for any help. This problem has only recently arisen, due to an upgrade (downgrade?) in either Win10 or Firefox?
