Hi beloved admin. Resource Sniffer is not good for me because it is sometimes wrong when I wanna download video on youtube, it gets wrong video :(( Long time ago, I see an extension named "Violentmonkey" of Maxthon, after I installed that extension, I continued install a script and then there is a download button under the caption of the video, I clicked on that and my video was downloaded, it was great. But now it doesnt exist. Can you show me the link of the script of Violentmonkey because I can not find out it? Thanks in advanced!
