Just go to where the video is located.
Wait a second or two.
Click on the 'Icon' for 'video download helper' and it will auto detect the video's on the page your viewing.
The information about the video's on the page your viewing is then displayed. Click on 'Download' for the video you desire and it starts. The progress of the download can be displayed, such as 'Bit Rate' and percentage left. You can then go onto another video and select it. Multiple downloads are allowed. I usually limit it to no more than four, and try not to wander off to far from the video's webpage, just in case my connection isn't at its peak.
You can also pre-set the options for the download.
I use HD, 1080 and MP4. If the video is not offered in 1080, 720 is used.
Bottom line. Easy to setup and use.

This is one of the reason I use Firefox because of this great add-on to download videos across internet.

動画保存しても映像に大きく有料誘導のQRコードが入る

only downloads a few seconds. use to work great but this year its been dog water.

Excelente programa para bajar videos de cualquier lado, con opcion de calidades si las tiene el video.

Somwhere after jun 2024 this required payment to remove an obscenely large watermark. no thx.

It requires you to pay, otherwise huge "watermark" is placed on the videos

good app-. the best for this question

大変便利な機能です。

it ask to download application to complete the download.
so basically it doesn't work, no idea why this addon here.
report it

Downloading is disabled or unstable at many sites.

Puts a big ol QR barcode over videos, makes most downloads useless. Completely useless extension now.

Deceptive and misleading. It says there will be watermark in the corner of downloaded video and that's ok. I'm fine with that. But... the "watermark" is gargantuan QR code that obscures significant amount of screen and instead of pleasure you will only have frustration. 0 stars!

very effective when needed

Sehr gutes Tool, einfach zu bedienen, effektiv und mehr oder weniger konkurrenzlos.
