The Video DownloadHelper add on for Firefox is HANDS DOWN THE BEST VIDEO DOWNLOADER I HAVE EVER USED! I have tried many different ways of downloading embedded video via separate programs, other add ons for firefox, even chrome extensions as well, and Video DownloadHelper is absolutely superior to all other applications that I have tried. It works right after installing it without any setup but it does offer a bit more control if you want to customize something, like file directories and the like. Most of the files I have downloaded are HD quality, especially in the last year or so. Computers are getting much faster and ISPs have been compensating for this increased capacity for speed and power, meaning websites are now able to use 1920x1080 sizes for their embedded videos without users experiencing the hiccups and buffers that they used to when streaming HD videos. Video DownloadHelper recognizes the 1080p quality and downloads the video in the MP4 container format, there is neither video nor audio integrity lost in the download. I'd give this program 10 stars if they would let me! I would say I use this far more than the rest of all my other firefox add ons combined.

wery good

我以前一直在使用，感觉非常好，我还想继续使用下去。

Es funktioniert bei so gut wie allen Videos, die der Browser selbst darstellen kann und ich habe keine Probleme gehabt. Kann es nur empfehlen.

下載速度快

The best tool i have ever came across so far.

It takes a while to download ADP files with video and audio aggregating separately, but it still works, and there are often equal quality formats for the same video that work as fast and fine as usual. Maybe that's a small price to pay for a sleeker and faster Firefox. Otherwise, after getting used to a few adjustments, I think this is still the best downloader around.
