Love it. does what is claims, very easy to use. Great piece of software.

Video DownloadHelper has been an easy to use and reliable tool. I was able to use it right away without needing pages of instructions and have never had trouble using it with my computer or any website.

下载次数达到600次，提高了工作效率，节省了时间，增强了效果，是不可或缺的帮手，会一直支持。

Works well, I use it a lot.

Works pretty well.

Works pretty well, you don't need an extension to save most videos but this extension has plenty of options to make sure you can download any video.

IMAGINE WATERMARKING A VIDEO BECAUSE YOU SAVE THE USER 5 SECONDS IN FFMPEG LOOOOOOOOL

超棒的组件

Absolutely must. This extension is absolutely great tool for getting those videos that you can need for making reports, school work and so on.
KUDOS to the devs - hope the work with Mozilla is great :)

It's very great plugin for download video. I can more download with write review. Thanks.

Downloads any video or sound file. Very good.

Maybe it's me as I realize that my skills in this area may not be comprehensive enough to use this extension but I installed it with no problem. Then I tried it and it said I needed a companion app and gave me two options for that. I tried both options, even having to tweak my security settings to allow the .pkg file extension. Then it finally allowed me to choose the format/conversion except being a laymen there are so many options that seamed so similar like mp4 1mb vs mp4 2mb. So by one I tried the ones I recognized as to not overload/overburden my macbook or the server or whatever can get overloaded. None of the formats, not even one actually downloaded. I gave up, tried another similar extension. One click to download the extension, then one click to select the format then a third and final click to download the media. That's it! The other one worked. Maybe this extension is simply too sophisticated for my average/adequate skills. I'm assuming it's me but maybe this review will help developers think about us laymen when creating extensions in the future. Cheers!

Downloads any video or sound file. Very good.

Spyware. VDH asks you to install an app. DON'T DO This. Your IP address is changed and rerouted to a bot with IP 37.1.188.237, located in Manila, the Philippines, GPS location 14.61 120.97. Various sites will refuse entry, telling you you're on a bot and at an abnormal location. Some virusscanners know this and act.I you are on Linux and have Redshift: the color temperature of your screen will give the time and temperature of the Philippines. To search a nearest shop location (entering postal code): doesn't work anymore. In case you have installed that app: only switch VDH on when needed and switch off after use, but never start your computer with VDH switched on. Or remove VDH and reinstall without the app? I'm not sure if the app is removed together with VDH.

made youtube videos unplayable
