Working and lite addon Rated 5 out of 5 stars

It is a working addon, doing what is described to do. Nice and neat.

I hope there would be an option to make the default save location permanent and not changing with the last saved location (which gets updated by Firefox too).

Latest version 1.8.9 not working with new YouTube UI Rated 3 out of 5 stars

This has been a great add-on that's allowed me to save a lot of bandwidth on video replays. However, the latest version isn't working. Google changed the YouTube user interface which I believe broke the add-on functionality. Firefox 64-bit version 50.1; Windows 7.

New version (1.8.9) does still work (as of February 2, 2017) Rated 5 out of 5 stars

I just went through the hassle of installing the dev version of Firefox so I could install the unverified extension - and it does indeed work. I was afraid that Google had figured out how to throw another wrench to (permanently) make downloaders not work. What happens if they move *everything* to adaptive streams, and not just the 4K content?

That's a good question. Downloading DASH files is not hard (you can already do it from this extension by going to about:config and changing extensions.downloadyoutubemp4.download-youtube-dash-enabled from 0 to 1). The problem is merging video with audio files, which usually requires some third-party software like ffmpeg.

Now it works Rated 5 out of 5 stars

Very Nice Rated 5 out of 5 stars

This is the only youtube video downloader that worked for me. Unlike many other addons, it doesn't rely on third party sites!
It's so light that you won't even notice that it's running.

Great Addon Rated 5 out of 5 stars

Doesn't work as of Jan 31 2017 though. Or rather, it only allows for 360p downloads.

Edit: v1.8.9 has it working correctly again. Thanks ialc as always.

I uploaded a new version (1.8.9) that fixes download issues you've reported. It needs to be approved by Mozilla and this might take a few days.

Essential to my business Rated 5 out of 5 stars

I have never rated an add-on before, but I just recommended this to a friend and I realized how often I use it. As a voice artist and YouTube creator, this has become an invaluable tool for me. I'm able to download my old videos and re-purpose them for future video projects, I can rip audio and use it for demo work for my voice over business, it's really a great tool that I use almost every day.

Falls back to "save as" 70% of the time Rated 5 out of 5 stars

I still gives this a 5 as I've been using this addon for almost 8yrs and never failed. But for the past 18 months or more, it fails to detect FlashGot, it opens video in a new tab, or it open the "save as" folder.

Everything seems to be related to video-quality.

It needs a complete over-haul -(
