Have been using this app for occasional higher quality downloads for years. Recently had some difficulty enabling the PRO features, but the developer quickly responded to help me solve the problem.

the pro version works very well

Easy to use, great tool.

为什么下载时候的文件名，和视频不一致

I love this plug-in extension add-on. Though it has not work for me as of late. Probably due to Youtube updates against Firefox's own updates. Hopefully the creator of this app can resolve this!!

A great add-on. Using it often. Quite happy with it. Recently experiencing very low transfer speeds but it is free so I cannot complain.

The best downloader for Firefox, and not by a little. The operating interface is still a bit obtuse for the uninitiated; the only reason no 5th star from me.

just wanted to say, if you really do it all by yourself, kudos to you, cuz thats a chunk of work. im a bum and penniless, but i figured a random saying thats impressive might boost your moral. continue improving, even if theres only one person left trying to better the world and themselves then theres still hope. however slim.
