Not work in macOS 10.12 and Firefox, only windows

superb, thank You for this add on Great I may record such meaningfull songs of mine, and funny videos, Thank You so much!!!

Same problem here. This extension used to be one of the best, if not the best one actually... but I'm now facing the "native application is not installed or not available" issue. I use Win10 64bit ver. 1903
Please check! Thanks!

Not working after one week: Streams were downloaded but resulted output file is missing or empty. This indicates issues either with downloaded streams (empty or has incorrect format) or with video converter
I deleted and reinstalled the downloader and the native aplications but stil not work?
Have you some experience how can use again?

It is only extension work with old and new FF versions. With native executable? Yes. And? Any other downloader solution is a joke, and on Chrome no way to download from Youtube. AVD is a VLC for FF. I use it for years an download several specific video which are hidden via cuncurent downloaders. It was only one time to have to use Quickplayer screen recorder intead of AVD. I am very thankfully about this production.

Tried about 10 other video downloaders rated even higher than this: easy youtube, video downloader pro, flash video downloader, etc etc etc...NONE OF THEM WORKED! Certain sites are increasingly being d***s about downloading videos and ANT Video Downloader is the ONLY one that works as of 6/12/19! Thank you ANT for such a great add-on! You deserve 6/5 stars, not this B*** S*** 3.8 that you're getting right now! WTF IS WRONG WITH PEOPLE?!?!?

Great addon. But can you please fix unusability when it's placed in overflow menu? This is how it looks like when is there: https://i.imgur.com/2KkZvp3.png

下载视频很方便，就是不能识别视频标题

這是個不錯的擴展，可以下載NICO和YOUTUBE的視頻，非常好用。但，有個很大的問題，如果是中國用戶，必須要先上代理，而這個擴展必須開全局代理才能下載，如果只用網頁局部代理，可能是因為它後臺要開啟一個程序？我猜的，導致不開全局代理後臺程序沒法繞墻下載東西，然後失敗。所以想請開發者把擴展改一下，能夠讓網頁代理也能下載。Please modify the proxy option and the browser proxy cannot be downloaded.

目前chrome和firefox下最棒的網頁流視頻下載擴展,YouTube貌似更新了後台網頁機制,導致很多下載工具插件都失效了,Ant也還能完美下載,非常難得.但依舊還是那個問題,用代理的話必須開全局代理,否則沒法下載YouTube等需要開啟代理才能看的視頻.不過能下載就已經不錯了.謝謝~

Dudes, WTF?? I have installed everything i can find and still dont have the native app. Where do i install the native app? I have register on the website and installed all three products but still cannot download because the "Native app" is not installed. Convoluted cluster!
