I don't know if what I am looking for is possible, I want JS, or any other programming method solution to detect the requests calls for a given url page, something similar to chrome dev tools
There is a site that displays videos, I would like to access through the video page url the playlist url, I inspected the source page but I haven't found it, it's been loaded after 4 -6 secs after the page is loaded, I could only find it in the chrome dev tools, under Network tab.
Note: Internet download manager & other firefox plugin could detect the playlist url. It should be some way of doing it.
Edited: I am open to develop chrome extension to capture the playlist link, similar to IDM chrome extension work.
I could do it using webRequest in chrome extension. I added this code in the background.js and it worked.
