The new version 3 is useless on a MAC.
I get the message "Warning: Native application is not installed or not available.". The link to the native application is Windows only.

OK, 3 years later ...... still under development. Either you are the slowes devoler I have seen or this is not truth. I do not beleve you are developing on a MAC version.

the old was easy to use，I don't like the new one。

zéro , aucun moyen de télécharger des vidéos avec sous w10 ce log qui ne fait que renvoyer a une page a chaque fois que l'ont click sur le bouton

I don't like being bumped to a new page now. I preferred the drop down list. I also don't like that I cannot tell what most of the things that I see on the new page are now.

allucinante!!! una persona si aspetta migliorie dalle nuove versioni, invece si ritrova uno scarsissimo sostituto. tra l'altro anche installando la vecchia versione non la puoi usare perchè ritenuta obsoleta, le nuove versioni inseritele dopo attente prove anche l'interfaccia utente non è chiara.. mi dispiace ma cambierò motore di ricerca

Really sad to see the old version gone. This one is idiotic to say the least...... PITA to use.
Last version was so well done. Simple and easy to use. Can't understand why the change.

It was the best the way it was. Just needed to update if for FF v57.

Oh well now off to search for something better.

wow this downloader has hit rock bottom. Barely supports youtube videos and only download format is webm. I use online downloaders now, at least I can get the videos in a format that is decent and not have to download other crap to make it work. Very disappointed in ANT, thought you would work harder to make a decent replacement.

[YouTube.com] 2016 Rewind: Amazing Places on Our Planet in 4K Ultra HD (2016 in Review) - YouTube

My most favourite add-on is going down down down, what happened? Oh no why this is happening to me? Please bring the old addon back in the new version of firefox........otherwise there is no use to it.

The older version was so much better, one click and the video download started. Now it's very complicated, i hope your team will fix it. Some of the people here say it's a waste of time and WHAT HAVE YOU DONE? Yeah thats right, we are getting more and more used to it that something that has worked great and was a super program getting bader and bader and shittier, but i hope you will make it in the old way and it will work with Firefox 57 like it did in the past. Sometimes the past was better.

Worthless .... Waste of time ... people don't want shit formats and players.
People want Just a Youtube download that makes a mp4 file, and this is NOT it.

Stay away, waste of time

for some reason i can no longer download videos

This used to be a very good downloader with simple one click downloading from the same screen you wanted to save things from. Now it opens a new page full of links to every tab you have open and most of the time the files don't work once you have them. I'm not sure why, but they decided to make their product unusable. I'm searching for a new video downloader no if anyone has suggestions.

Wants to install another program, which I can't find be searching ant.com. I don't download programs from links.

Con la actualizacion mas reciente de mozila ya no es funcional esta extension para descargar video para mi era la mejor de todas y hoy ha muerto byeeiiiiii

A versão anterior que rodava no firefox 56 funcionava perfeitamente. Agora não capta mais os vídeos na versão 57.

tool bar missing? takes 2 clicks instead of the old 1 click

Really really bad, it doesn't work and the version in the older versions was so much simplier and better i hope the ant.com video team will fix it and will make it in the old way otherwise i think i won't use it anymore

it works very badly in Firefox 57. It does not look anything like its previous versions. It will have to adapt well to the new Firefox.

I am not able to download videos neither from youtube nor from other sites via 3.0 version on firefox 57 version.
Please keep the old one, it is easy to use.
