When I try to download a 40 min video, it could not download the video. When I tried to download a 2 hour video, it would not download. It could download 6 minute videos, though.*

If you're using this to download shorter content, then this could work for you; but it you're planning on downloading longer content, then this browser extension may not work work for you.

Though, personally I wouldn't like to gamble on whether this extension may work or not, each time I attempt to use it, so I would like to think it is better off finding another extension.

*It came back with an error message. I can't put write the error message here because Firefox doesn't allow URLs in reviews.

Jelenleg nem működik!

Internal error all the time, and even if it succeeds at starting to download, it fails all the time. I only managed to get 1 song after trying about 10 different ones, multiple times..

Poor interface - It doesn't give you options for the download resolution or the fps. There's no progress bar, and it just seems to open up a Youtube link downloader in an isolated frame.

The add-on takes me to an external site to download the video. It takes forever to download even a low-quality mp4 and I have a very fast internet connection.

Still, not works for some video.

Not realy accurate.

This extension used to work great but only up to a month ago (today 9/22/18). I installed it in my Firefox. Nowadays it works about 30% of the times and I basically gave up on using it.

It WAS a GREAT tool! Not anymore!!!

Used to work great but no longer works after Firefox update. I thought that the purpose for an update was to make things work better!

It can't download 1080p or higher videos.

Daily limit? Fuck off

This DLs video without a problem but if an MP3 is longer than 27MB, it stops there. Don't think it used to do that.

Maybe you could look into it, Mr Developer?

Unreliable for me. I tried to download OPUS audio and the downloads failed half way through.

Wants me to "Like" them before I can download.

UPDATE (reply to the developer): Excellent, I gave you an extra star for that. If I get some time, I'll test it again and maybe update my review again...
