This has always been a great addon, but over the passed few months it would randomly throw a "output file is missing or empty" error when downloading YT videos. However, the last week I haven't been able to download a single video. I've updated the native app as-well.

So, even though I know it's not the app and probably YT that's changed something, downloading doesn't work at all anymore.

I like how compatible it is with so many web pages. It seems to almost always get the video out. But a BIG problem and which can not find others complaining on, is that in every single video that I download, there are audio gaps every x seconds, but the AV stays in sync. When played in Chromium browsers, no gaps, but the A/V gets progressively out of sync. I'd like to share video's that I suspect will be deleted later, with friends, but not with audio gaps or AV desync. Anyone know a solution?
Anyone else: Please tell me I am not the only one.
Developers: Have you heard about this issue before?

Está bien y sirve para descargar videos en streaming que suben particulares.

No sirve para descargar Netflix, HBO, Filmin... ni nada de eso. No te los coge o si los coge se ve pantallazo verde.

Was working fantastic till the lastest FF update. now I need to disable it, or else can't do anything

It seems like that has memory leak problem on the firefox 100.

After I upgraded ff to latest version, I've found that memory usage always become to 100% in 3 min when startup.

And through some check, I think that is caused by Ant Video Downloader.

Please check this issue!

Once it used to be a great app. Now it's kinda crap. Uninstalling or resetting it helps only for a while. The moment I enter a site with loads of vids the app inflates RAM to 20GBs and more.
Devs, revert it to the state when it was faultless!

It worked very well up until a few weeks ago. Now any video I try to download, I always get the same error: "Status:Failed Extension request doesn't contain required field media/descritptor" Any Ideas? Already tried reset

In past are the best addon, but now i dont know what happen, download too slow, i have 600 Mbps of connection and only reach 50 Kbps, for download 1 video of 30 minutes need 40 minutes, you can solve this problem?

Works great for downloading most videos.
Gave only 3 stars because of the annoying tab "Ant.com" that pops up now and then after the add-in is upgraded and when you restart Firefox. I wish I could turn that off!

good not bad

Worked fine till about 2 weeks ago when firefox updated. Then pushing the icon, appeared as pushed, showing the place where the window should open but nothing appear. I removed addon and reinstalled, I even removed entirely Mozilla Firefox and cleanup profiles folders. The result was to work for another day. Too bad, it was a good program.

Liked it in the past. Doesn't do the whole job anymore

Ant Video downloader, one of the best downloader, once every five or six downloads get a mkv file from YouTube with corrupted video (audio can be heard, the video cannot be displayed: black windows).
It seems that the file has not the right size because of video lacking.
Then Windows Explorer (Windows 10) is blocked when I want to suppress the file.
By the way please don't modify original file name in saving.
