I have internet filtering on my computer and the filtering company blocks all video downloads from YouTube and it only leaves the option to watch. The question is whether someone can bring or create a javascript code or another suitable language that I will put in a bookmark in the browser and when I click on the bookmark the video will be reduced to the highest quality or it will be Some options. It is very important that the code does not work through another server, because of course the other servers are blocked. It must be that the code itself downloads the file. Thank you very much.

I tried several times to download the video and could not use software
