95% of any video I see can be downloaded. You need to choose the right download link on a page, try them all. The companion app downloads faster and I haven't noticed any suspicious connections or bad behavior from it. Excellent add-on!

方便簡單!!實用!!

Medianamente funciona, algunas veces dura demasiado o veo imnesesario convertir el archivo en YT, la interfaz no esta intuitiva, no ha recivido actualizaciones en un buen tiempo

qiuck nice &very good

Very Nice Soft.

Programma eccezzionale - scarica l'impossibile, supera i problemi di Firefox NECESSARIO 200%

first it says you need to have an companion program then if you wanna convert the file to mp3 or something you need pay 12$ just use yt1s.com

Like all good software Downloader works well, is problem free and and does what it says on the tin. I would be lost without it.

Hands down,
Video Download Helper is the best program around. Easy to use, select the video you want to download and click the Video DownloadHelper's icon and click on the Video you choose and then click save. That's it. Simple, easy to use. 99% of the time it will download the video.

really nice Add-on, helps a lot! Tks!

This add-on is very simple and easy to use.

It only allowed 1 download; the first download. The rest of the times I tried to download a video, it wouldn't let me. It kept giving an error. I don't have time to deal with this, so it's getting uninstalled. It said, "Failed aggregating. The file might be corrupt." How could the file be corrupt? It played when I clicked play. I also don't like that I had to download TWO apps instead of just one.
