I have to agree with most people, before Firefox v.57, this add-on was absolutely amazing. I rarely had any problem with it, and I could always find a work-around if the video I was looking for wasn't able to be downloaded on this add-on. I just had to use another mirror and that's it.

Since Firefox v.57, well, it got knocked-out pretty hard.

It's still managable, but the UI is not as appealing then before. It's hard to figure out which link is what, I happened to download 3 ads instead of the video I wanted... the easiest solution is just download every link and remove the wrong video afterwards, which is kind of not efficient, but it still works. Nevertheless, it's annoying and disappointing. I know you are currently working on making it availiable on other popular browser and you're trying to make some hotfix but Firefox is being a meanie with you and all.

I won't be as harsh as other people because this add-on still work! It's a bit more of a task management... but it works.

If you manage to rebuild the AVD into what it was before, it would deserve it's 5 stars and beyond, until then, I can only afford 3.

You probably already thought this through but maybe starting from scratch? Sometimes it helps.

Best luck for you, hopefully it will rain down 5 stars on this add-on in a near future.

Why can't we get it plain and simple like before? Now it requires you to install a Windows program and grant far too many privacy rights for my taste. I guess we will have to uninstall it and find another one.
I would recommend to stay away from this extension until (if) is fixed again.

After having read detailed explanation (https://support.ant.com/hc/en-us/articles/115005568983-About-the-new-Ant-Video-Downloader-3-0) I regret my previous harsh comment and thus I have increased my rating.
I will keep checking for new versions of Ant, and I have trust that the ease of use of the older version will be restored soon. Please ignore my previous comment.
