I am very content with it - despite all the negative feedback.

The UI and the process of grabbing the video you want to download is a little confusing at the beginning.
But once you got it, it is very easy.

Very powerful downloader, grabs almost anything ;-)

light and powerful little app that easily grabs pretty much anything. It's fast and unobtrusive although some might find the interface a little daunting the top panel provides all the documentation you could need.
It's obvious that some serious effort goes into keeping this ahead of the game. Thank you and well done!!

Not the greatest ui and has its issues, but it has consistently worked for years on the sites I use it for.

scheme of getting the resources is probably not the best, but it works on 100% . sadly it doesn't work on android . 5 stars because of the wrong rating balance .

takes some getting used to but will grab videos most cant and doesn't require questionable additional downloads

非常方便（Very convenient）

Perfection.
While all others failed to catch video.

I use it a lot, it will be nice to have better filters but it does its job

WTF? Why did this developer think intercepting all current http requests was a better way to scrape the web than parsing html? You have to refresh pages for it to see anything, then it only shows you http URLs, and there's no way to specify which tab you want, it's browser-wide...so any pages sending AJAX requests in the background get detected. Maybe someone has a use for this, but I don't. +1 star because it does actually seem to detect media using this cockamamie method.

recien lo baje espero que sea mejor que el anterior

I keep removing this add-on, but it keeps on reinstalling itself! at least once every 2 to 3 weeks, it is back.
