I do know a workaround for this but it would probably require access to the websight anyways.
Basically, you can embed the videos from dat websight into any webpage. Once you embed the video into the webpage just refresh the page and you are free to browse the video. Only thing you would need is the link to embed the video which you would probably need access to the websight to get.
I haven't tested the full method to see if the workaround exists if you have zero access to the websight but I used to just create a single page with all my favorite videos embedded on there so I could have quick and easy access to them.
