Unable to update my firefox quantum web browser 64 bits windows 10 even though already latest updated

more options

I am using a windows 10 pro 64 bits pc, ever since I installed the new Mozilla Firefox Quantum 57.0.4 (64 bits), the Firefox browser keep on prompting me that "Firefox can't update to the latest version". I try to update it through Help -> About Firefox -> update, it keeps on failing to update to a latest version. Can please help?
