It
is a bit old, but mainly I have a lot of flash and java stuff blocked, which has a tendency to fuck up a lot of streaming sites. For a few of those sites, you can use a 3rd party downloader like Jdownloader2, just copy the link and it will parse it for you. I don't like that it puts everything into its own subfolder, but that is handy when you go to an image site. For example, go to page one of a search on Rule34, and copy the url, and it will save every image in the collection into one folder, which is nice. But when you are only getting one file it can be annoying. It also automatically tried to extract archives, though it issues with 7zip.
I keep meaning to try the stream site with various other browsers I have, but it's hard to justify the time, when I should be watching programming tutorials or studying gameplay/UI possibilities.
