При попытке скачать видео с ВК получаю сообщение "Video not found. You may need to start playing the video on this page or refresh it before attempting to download. In case when video is playing but still not detected, please report us so we can check it out and make a fix". Firefox 67.0b7 x64, Windows 10.

Its nowhere near as good as it has been in the past, but it is still passable even if it is extremely slow.

older version used to default download location and used to give a visual of the download progress
still a good addon tho...i just wish those features were still available

Why there is no native app for mac os X ???

Bad, terrible, it barely recognizes a video to download, and it doesnt work properly, the older version was really good, it was a terrible mistake to update the mozilla browser, because the older ant downloader version doesnt work good on the new update version of mozilla

Most times says download failed

It does technically work but the interface is an unintuitive nightmare. I didn't even realize the addon was doing anything at all until I finally scrolled all the way to the bottom of the ridiculously long list of videos it generates (I use a lot of tabs) and found out that, yes, it was actually doing what it was supposed to do. Such crucial information should be displayed at the top of the tab, not the bottom.

I'm sure the development of the new version of this addon is still in the early stages(?) but the transition has been obviously been rough, to say the least. I really do miss the old pre-Quantum version.

I wish we could also download YouTube videos we purchase, with this extension.

It works. I have used ANT products before and it went well. It took a few moments to figure it out though. Go to the video and select the resolution you want. Then click on the download arrow in the browser. Then find the current video at the top of the list in the downloader window. it will give details and click on "download" at the bottom of the details. It will show the download progress at the bottom of the page. When it is completed it will appear in the ANT folder in your Downloads file folder. Done. Thank you Ant. ;-)

After the last update,Ant Video keeps erroring out EVERY download - Sorry,if this is the best you can do,then you need to quit

Não funcionou corretamente.

Since they started to use that installer downloads are incredibly slow (~60 KB/s). Downloading videos at that speed takes way too much time.

This WAS a very good extension.
Hopefully it will be again--soon.
Currently the thousands of videos that I have downloaded over the years are mostly unavailable. If any future upgrade of this extension doesn't make those old files available again I feel I may as well start from scratch with another extension. I hope it doesn't come to that, though.
The mechanics of one downloader or another aren't really all that important to me--the real value is in those old videos. If they are "gone" I probably will be too.
