Seems to work, but inexplicably only allows to download 720p and 360p with audio, but not the most storage-to-quality proficient 480p format with audio included.

Здравствуйте. Перестало работать на ВК, ОК и ютубе. Не скачивает ни музыку, ни видео. Пофиксите, пожалуйста, тогда переправлю рейтинг на 5 звезд.

作者NMSL，画质远不如在线播放不说，还需要额外下载第三方软件，最恶心的是未注册用户会给你视频打一个超大的二维码，还会恶意捆绑你的书签栏，删掉书签重启浏览器还会出现，第一次见这么恶心的插件，如果有人中招了，排障模式中的翻新Firefox、新建配置文件、常规卸载重装都是没有用的！一定一定，要备份好资料并常规卸载之后，把关于Firefox和Mozilla的一切注册表和文件全部删得干干净净！重启电脑后再重装才有效！希望被坑的人都能动手举报这款垃圾插件，最后祝福插件开发者全家死光光。

Removed for its discrimination of the UK.

By far the best video download add on for YouTube in Firefox. So easy to use. My favorite ever.

attention, même une fois supprimée cet addon rajoute systématiquement le site dans vos favoris, comme un virus !!!

watch out for this one. at first it seems great.. but now its suddenly changed.. the 'download' is gone.. trying to do the same simple actions 'download' now brings up a dialog which says 'converting'.. i hate developers who try and pull fast-ones.. 'save-from.net' is that you? perhaps you need to come clean and explain what changed.. because for now your little downloader is disabled.. there are plenty more add-ones that have this functionality.. you are nothing special if you play tricks.

배움에 도음이 됨니다

I really appreciate your hardwork. It's the best out there. But really want it to work on Twitter. Do you guys have a plan for it?

Is not removable. Changes Browser settings, similar to malware.

Even if addon is deleted the bookmark appears all the time again after reopening the browser

I freaking love this thing. Makes youtube just so much better.

Расширение работает, единица за паскудное отношение к пользователю. У кого не удаляется закладка - в папке с Мозиллой откройте папку distribution, в ней удалите файл policies.json и перезапустите браузер
