I'd like to rate something else because the stand-alone free software is very well made for standard download needs, however this extension doesn't work at all with Youtube or Vimeo, it doesn't find anything (neither the software).

no working with https://www.facebook.com/HumorbyEduardo/videos/835353556803311/

Not to added

This program CONSISTANTY downloads about the first 4 minutes of a video.
NOTHING IS VIEWABLE AFTER THIS.
Windows Media Player ERRORS OUT and WILL NOT go past the "dead" spot.
This is quite consistant, and is observable with ALL of the Videos I've downloaded.

I Can't reccomend a program that behaves like this. I have received NO feedback from
the authors.
