Every time Firefox opens, I have to re-download it. What's wrong that it won't stay on my browser.

Tried mp4 download, avi, - each time asks to install 3rd party software, what??
"Companion application required⊗
This operation requires an external application to be completed."
U serious? Addon got such extensive permissions and still asks for shady 3rd party software even more? Instant delete.

since it needs to install another compainion exe file

Very straight forward interface to get most of your videos

I rate 4/5, because this is the best video downloader for any site out there. however, one problem that needs to be fixed, is that... when you watch a livestream through youtube, this plugin causes the video to stutter/buffer every few seconds and youtube becomes unwatchable. Every time i watch a live youtube stream, i have to disabled this addon for things to work normally. I've noticed that this add-on adds hundreds of items to the video download list during a youtube live stream, and believe this is what is causing the video problems.

funktioniert super

Пользуюсь уже пару лет, единственный минус не все файлы с Ютуба может скачать. Но те ролики которые DownloadHelper'ом не качаются, не скачиваются и другими загрузчиками.

ease of use

不错，继续努力改进

Not good, since they started asking for an auxiliar app to be installed the quality decreased immensely. Currently it is not working.

Have been using VDH for quite a while and it is very reliable. I have had no problems with it at all. Highly recommend this addon for anyone.

Works perfectly with Firefox on almost any site I have visited.

Overall it is an excellent app. I have had no trouble downloading with it.

覆盖的网站很多，如果再自带个下载工具比较好

good

6.3.1 works great with Palemoon 29 , waterfoxClassic and Basilisk2020

Best Addon!!

Was brilliant until the companion app update, that took a lot to update & now fails every time, I'm not particularly tech savvy but the update instructions were near useless & when complete VLC player would no longer play video, so had to reinstall new version to get that working again, no idea why that happened but it was fine before the update.

Used to be GREAT! I've been using this extension for years and years. I understand that the way it works had to be changed because of changes from Firefox recently, but now it's a mess. I'm using Firefox on a MacBook Pro with the latest Mac OS.

1. No way to tell if a download is happening. I guess it's doing it with the companion app? All I know is I ended up with a dozen files in my DWHelper folder with no indication they were there before I thought to look.

2. HUGE QR CODE WATERMARK. Hey, here's a great idea, let's ruin your video for you and charge you to NOT fuck it up. Fuuuuuck that. It doesn't warn you about this when you add the extension or download a video.

Look, I get that the developer has done this huge product for free. But I'm unemployed and broke and want to save some videos WITHOUT a watermark on them. Fuck me, right?

Yeah, this extension took a huge nosedive to uselessness. There are free video download sites for places like YouTube that you can find with a simple Google search. I suggest using those.

The best!
