I could not reproduce this issue using Windows 10 Pro(64-bit) on Firefox Nightly 63.0a1(2018-07-12) or Firefox 61.0.1(2018-07-04) My CPU usage doesn't go above 25% while downloading a file using Video Download Helper.

Could you try and reproduce this issue in safe-mode? You can find the steps to do this here:

Also could you please try this issue in the latest version of Firefox Nightly?
