after watching the video online (make sure the video is loaded! ! )-Click Tools on the browser's main page -----Internet options-General browsing history settings-View files (a folder will be opened, which is equivalent to the cache folder of your Internet, and there will be countless files in it)-Generally, the largest ones are arranged according to size. Then copy it out (everything in this folder can only be copied one by one). Pure hand play, give points:)
