The 'date' detail in Windows ('Media Created' in Properties > Details) of every downloaded file using VDH is now 12/31/1969 7:00 PM. Because they all exactly the same, it makes sorting by 'date' impossible.
While a file is downloading the '.mp4' and '.mp4.part' files have the correct time, but once the download finishes it changes to 1969.
Happens in Firefox 61.0.1 with VDH 7.3.4 using both the browser and companion app download options, also happens in Chrome 67.0.3369.99 with with VDH 7.3.4.
I tried reinstalled both the extension and companion app in Firefox and it still happens. It seems to happen on every website I try and and none of the files I download without VDH are affected.
