It worked very well up until a few weeks ago. Now any video I try to download, I always get the same error: "Status:Failed Extension request doesn't contain required field media/descritptor" Any Ideas? Already tried reset

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

Worked fine till about 2 weeks ago when firefox updated. Then pushing the icon, appeared as pushed, showing the place where the window should open but nothing appear. I removed addon and reinstalled, I even removed entirely Mozilla Firefox and cleanup profiles folders. The result was to work for another day. Too bad, it was a good program.

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.
