Very useful if you need a video to be accessible off-line. My part of the world doesn't have total wifi coverage.

Great to use, I'd recommend it

Uzun zamandır kullanırım, son güncellemeye kadar problem yoktu. Şu an çok fazla kaynak tüketiyor. Her video indirmeye başladığında 1 gb ram tüketiyor. Bu yüzden artık idm kullanıyorum.

Me sigue resultando muy práctico.

geweldig programma

除了好用，想不到其他可形容的

下載方式很直覺，也可轉換成其他格式

還沒碰到無法下載的網頁

Does what the other video downloaders can't. Excellent add-on

还不错，下载比较方便，识别率高

Sometimes I need to learn from videos yet don't have Internet at home or with my laptop while riding public transportation. Of course. it also helps me catch up on other things I like YouTube channels like Anthony Brian Logan, thecomicbookcast, and Mark Crilley.

i has all the tools that i need to download and save

企，鹅，学习视频不完整，所有视频都只有5分钟，有解决方法吗？

幅広い動画サイトに対応していて操作も簡単。愛用しています。

Pela rapidez e facilidade de utilização o Vídeo Downloader é uma ferramenta indispensável, pronta num simples click.

J'aimais bien ce module à ses débuts, quand il n'y avais pas d'alternative en ligne. C'était léger, rapide, simple et bougrement efficace.
Mais aujourd'hui c'est devenu de la merde. Il faut maintenant obligatoirement passer par l'installation d'un convertisseur useless (alors qu'il a toujours fait sans auparavant) et ralentit CONSIDÉRABLEMENT la navigation YouTube sur Firefox ESR. Regrettable.

非常好用

very good

Very smooth use

exelente

Excellent piece of kit. Seems to work when others don't. Been using it for some time now and don't recall having a problem.

It downloads alright, though it does it at some slower speed. So it interferes with the possible downloadspeed somehow.

Secondly, much worse, aggregating sound and the movie (combining of the video file and sound file) takes forever. For a five-and-a-half minute video at 720p it took the plug-in just over 30 minutes! I'm on a I7 3820 @4.1 GHz. FFMPEG is at a 10% CPU load. Such a long aggregation time for this size of a video is not normal.

Thirdly, it didn't finish a few aggregation tasks, I wonder if the browser has to stay open for the duration. Also, imagine if it is a huge file. It would take forever to aggregate.

Setting the download folder fails. Something is wrong with the interface. Sometimes the settings interface closes by itself! What the heck LOL? Clicking on a custom download-folder sometimes works - so it seems - but checking it twice, your option has been deselected again. The settings page needs work.

Finally, the location of the downloaded sound-file (which needs to be combined with the video) isn't known to me yet. It's somewhere. I'd rather like to see everything downloaded in one folder, including files which are just intermediary steps.

All and all, this add-on has so much potential - it also downloads 1080p videos, but the aggregation-time is killing me.

Edit: ARE YOU EFFING KIDDING ME? Now I know why it takes this long to aggregate.
It adds a massive QR code in the top left corner of the video!!!

Also... the video was downloaded in 720p, but the remaining result is is also in 720p... with a bitrate of only 436 kb/s! In other words it looks like a bloody 320p video now, despite the high resolution.

Needless to say I'll uninstall this absolute rubbish in a minute.

Fonctionne parfait sous Linux Mint 17.1 avec le bureau XFCE ! Merci.
