for several years, since I found this extension, the best for downloading videos of almost any site. The experience have been consistent. When the video site technology have changed, vdh has adapted to offer same functionality. i think that at least once, I made a donation: This piece of software is great. Now that I mention it, I will donate again. I sit at least once a year to pick up the free software I use frecuently, and vdh is mandatory to include.
