Does anyone here use a browser extension to download videos, primarily from YouTube? For years, I used Video DownloadHelper on Firefox, but YouTube changed things, so it typically won't download audio. VDH offers a paid version, that MAY allow me to download some videos with audio and without the watermark; but there seems to be a significant split in the user reviews, suggesting it either works well or doesn't work. I don't mind spending the money, but am leery of the whole setup. Some people pay and don't get registered and some say it doesn't work on YouTube anyway. I've tried a few others and they don't seem to work either. There was one that was promising, but I think I messed up the setup somehow. It's called YouTube Video and Audio Downloader (Dev Edt.). There was some adjunct audio processor that didn't seem to install or work properly.
