This is the premium video download extension. It specializes on YouTube, but works most other locations as well. It allows either the browser or the custom helper to do the actual video download. I believe the reason it is the best is that it uses local resources instead of attempting to oversimplify the interface for the user (requiring remote server, etc.), but there are many reasons it is superior - customizable, merges audio-video streams, extract audio or video only, download multiple videos parallel, etc.

Excellent add-on!

Simplesmente demais .... o Melhor que existe .

Very useful, intuitive and easy tu use.

Excellent add-on!

Amazing tool!!!

Excellent add-on , highly recommended.

很好 很方便

I had to make an account just to review this. I am not sure what the people talking about watermarks or it not working. I do believe I needed to download a second program but it walked me through what I needed.

This works great for grabbing content from my Fans site as well as from my schooling site and has been working just fine on 75% of content out there. Sometimes you have to watch the content you are grabbing in order to grab the video you want.

Some things this doesn't work great for but I have yet to find anything better.

使用至今，數年如一日，簡單、好操作，大多數的影片都可以下載加上又是免費軟體，真的是值的大力推薦！

Ottimo: video scaricati correttamente e nessun problema.
Consiglio!

Some people have been complaining about watermarks on videos with this extension, but I haven't seen those, and besides I mainly use it to download music, which it's really good for. It doesn't put extra stuff into the file name that I have to clean up, I can direct the files into different folders, there are a lot of different options in general, and it's relatively fast. It's made downloading music much more convenient for me than when I was using random, buggy, slow youtube-downloader sites- I highly recommend it
