Well obviously you could watch it on the website, but if you're like me you may want to refer back to it once in a while, so yes I do download the files. My default browser is Mozilla Firefox and to protect me from any/all adverts and annoying trackers I use the Firefox plug-ins of Adblock Plus and Ghostery. Both are absolutely brilliant at what they do. Try that site without an ad blocker. Good luck trying to get to the video file..! The downloader is called Video Download Helper, and that's also a Firefox extension. It's not 100% perfect but it is so little trouble that I use it over others. It seems to be able to download almost any video, is highly configurable, so that ignores things I don't want, plus it can convert as it downloads, if I want. To download, start to play the video. This triggers VDH into recognising the one you want [a 3 sphere icon starts to revolve on the browser taskbar]. Right click on the icon and you'll be presented with menu. Near the bottom will be the option for downloading [you'll get the hang of it]. Once the download has started you can leave the website if you want to, or start the 2nd half if there are two files and begin to download that in the same way.
If you can get all those blocking features with the Torch browser then continue to use it. I tend to find that Firefox is still the best all-round browser out there. It's not the fastest, but it's still quick enough. It's highly configurable and safe, and it has simply oodles of plug-ins and extensions. Plus, it's straightforward, so there's no quirkiness to it and no surprises.
