used it over years - but if a full-HD Video from youtube loads with 500kb with 100.000 M/bit connection I am surprized and not happy. What's the reason for that? It could not even streamed with that speed

In past are the best addon, but now i dont know what happen, download too slow, i have 600 Mbps of connection and only reach 50 Kbps, for download 1 video of 30 minutes need 40 minutes, you can solve this problem?

Works great for downloading most videos.
Gave only 3 stars because of the annoying tab "Ant.com" that pops up now and then after the add-in is upgraded and when you restart Firefox. I wish I could turn that off!

good not bad

Liked it in the past. Doesn't do the whole job anymore

Ant Video downloader, one of the best downloader, once every five or six downloads get a mkv file from YouTube with corrupted video (audio can be heard, the video cannot be displayed: black windows).
It seems that the file has not the right size because of video lacking.
Then Windows Explorer (Windows 10) is blocked when I want to suppress the file.
By the way please don't modify original file name in saving.

Seems to work pretty well. Default save location is the "c:\Users\username\Downloads" folder even if you've moved the library to another location. Seems to be slight pulse effect between video segments on stream captures.

meh.
tried using it. instantly demands a companion app.
downloaded that.
file only downloaded as mkv no option for mp4 given.

When it works, it's great, but lately it stops in the middle and then says "user cancelled". In addition, whenever the native app is updated, it doesn't recognize when I install it. Instead, I have to uninstall Ant Video Downloader, close the browser, reopen, and reinstall.
