i'm glad, thanks!

In chain watch addon is creating another "download" unclickable button so after 10 videos watched in chain you got 10 green buttons. They dissapear after page refresh.

Good and fast downloading...
but some smaller issues are to be corrected:

1) completely freeze all the opened tabs on my navigator, Firefox updated, (not the computer) while converting the video.

2) creates a ghost image of the "Download as" button each time I change the YouTube page.

Not HD, but it works. First download had the wrong language, next one was fine and quick. Think the language problem is the new YouTube auto translate they started doing for everything. So if it was uploaded from Germany, downloading in the US will probably be dubbed German.

So far worked okay on one video, but I have two computers and it only works on one of them. In fact, installing on one computer made it work on the other. I think that's a bit of an issue, as I use the other for work.

Good. Just missing the MP3 option, can't find it.

GOOD

Works for now, no watermarks like VideoDownloadHelper. Will update review if anything mishaps occur

My linux PC is pretty old, and it took a while, but this extension was able to convert and save a 35 minute instructional YouTube video to a small mp4 format. It worked well, but I had to scroll down to below the video to see the progress this extension was making in conversion and saving.
There is one bug - if I click on another YouTube video in the same window, and try to convert and save that video, it doesn't -- instead it downloads, converts and saves the original video I viewed in that window, making another copy of it.
It seems like I have to close FireFox before trying to download another video.

Definitely the best YouTube video downloading extension. I think 4k (or at least 1440p) should be available for donators.

On y arrive mais c'est lent; il faut se connecter sur mozilla pour donner l'avis.

After a longer period of hick-ups and disrupted functionality it's back on track. When it works, it's easy to use. Recommend!

Works well, but keeps doing pop-ups to rate... repeatedly!

Can download YOUTUBE videos now. However all videos downloaded afterwards are repeats of same video and a green box "download " appears. How can I solve this?

It's fast and convenient, but unfortunately it didn't bring in the download title

Glad it is back and working. It works well for what I use it for: Podcasts which I want for mostly the audio.
However, it seems to keep downloading the same file. Not sure what is going on, but I have to close YT after each or it just downloads the same file over and over.
But it is working! YEA! I have zero to terrible wifi so when I get someplace with better I try to download these podcasts, so glad I am able to do so again.
