So ..it has come to this huh ...
As a user of this extension for about 10 years ...a couple of years ago (2021) when they did the update to the new interface style etc. I immediately warned people to not use it.
Its bad, breaks everything, I reverted back to the last oldest version before that very update ... and I am still using that very version (4.9.2) right now.
I find that it still works good and better then any later version ever could.

I see things havent exactly gotten better since the last time I checked in here.

I also see some people asking for the native app but can't find any. I still have it.

mediafire.com/file/3pzb6vrwhsg6ahr/AVD_4.9.2.rar/file

This rar includes the original 4.9.2 addon installation files for Firefox and the matching native app.

For those interested;

Uninstall any current version of the addon and native app.
Simply extract the .rar
Drag the fx.xpi file into firefox, and it should pop up asking to install
Install the native app if you want

But in Firefox, disable Auto updates on this extension, it just ruins it.

In case you were going to want to try .... I can not guarantee that this specific native app version works with a later browser addon version either. It might just start crying about how that's not up to date. I am not gonna go through the trouble of testing it, I just don't care enough. There are other browser addons to begin with as well.


Now if I could only get Mozilla to stop making stupid changes nobody asked for to begin with as they have done in the past few years ... we'd all be happy campers.

ITS DONT WORK ANYMORE

Elsewhere on this page, the developer has announced this extension is discontinued:

"Sorry to announce but Ant Video downloader is discontinued and will no longer be updated. Support is closed."

It requires you to install a shady desktop program for it to work. What's the point of installing a web extension then...

I give it 5 stars because I tried it against another download app with the same features but the latter did not give me a very good result. I see that in both apps, the video is downloaded in segments, but in the latter the contrast between audio and video is very noticeable. On the other hand, in this one it gives a better result, but even so there is a small cut in the image at certain moments of the video. I have downloaded a 20-minute video in both apps, this one has a better performance but visualizing the result, I still think it needs to be fine-tuned a bit more.

Das Addon funktioniert nicht mehr und lädt auch keine Videos mehr herunter.

Useless, You Tube/Google no longer alows downloading, even where it's perfectly legal, under jurisdiction.

Best downloader ever ♥

It works but a step by step tutorial on how to use it is completely needed. Even on the Ant Video Downloader official website they can do a good tutorial (a detailed one) they should do one.
How to use it?: You have to use Firefox (won't work on Librewolf), install the AVD native app on windows and then install the addon Ant Video Downloader on Firefox. Then go to settings of the addon and allow sending data to the native app cookies on privacy settings. After all that, open or refresh the website with the video and now you can find the video info in the addon icon, select the resolution and download it.
