兼容性好，推荐使用

这是我用到的最好的视频下载工具！

This is amazing. I was spending a ton of time downloading things one at a time, and I just realized now that it will download 6 things at once, and if you add more it'll queue them for later. It is fantastic. Between this and youtube-dl, I can download everything.

how amazing add-on to download video easily

War einfach zu installieren, arbeitet recht ordentlich für meine Zwecke, erleichtert auf jeden Fall das mühsame Suchen in Browser Cache.

Good

VDH has been great up until the 7.3.9 release. It then started behaving bad, as in starting, but never completing video downloads in linux. I tracked this stopping to a build with a library(GLIBC) version that is ahead of many linux distributions. Researching in Google, VDH personnel are claiming that it is not their problem and are doing nothing. GLIBCs normally work if the program build is on a lower version than the distribution. It seems like VDH only needs to build using an earlier GLIBC version.
4/17/20 update -- I checked a windows version and I get the same strange behavior of hanging in the middle of a download forever. Manually stopping it in windows, unlike linux, does not result in any error message.
5/9/20 Loaded up Coapp 1.5 and tested again. Did not work any better. Still getting the same errors(below) and only ".parts" of warying sizes.
Errors:
Exit code: 1

Thank you for this amazing software. It's incredible how easily and quickly anyone can record data!

it is very good

If you don't need to convert videos, and I usually don't, this is a great add-in. Yes, it requires you to pay for the conversion part - but I've never needed that bit; I use it to save videos from YouTube that fellow crafters have made and I do recommend this addin.

Changed from a useful app to a cash grab. Uninstalling.

muito bom

Después de horas descargando un video para quitarle el ruido y poder oir bien la conferencia resulta que te pone una marca de agua y ahora lo que no puedo hacer es verlo bien. Vaya perdida de tiempo...
Además es incomodo de usar.

flashgot was my all time favorite download addon, but firefox new architecture killed it (for sure to much efforts to implement. i still was happy, cause this time was spend to noscript, an other project from the creator of flashgot).
then this video downloadhelper addon was heavily promoted on firefox addon website, even if it was just a dim light compared with its bright predecessor. i installed it cause for lack of alternatives and most of the time, it did its job, even if it had sometimes issues and wasnt as compfy as flashgot.
and now it demands money (30$/20€) to remove a watermark, that itself has encoded in the downloaded video.
the new art of blackmailing! time to move on..
