Version 5.7.27, Firefox 50.0.2, Linux

I love it. It's very quick, but for some reason Firefox frequently disable it, claiming that it's not verified for use in Firefox.
Removing it and reinstall it solves the problem for a while.

This review is for a previous version of the add-on (5.7.27).

Thank you for this addon. I love it. I can now download 1080p videos.

Hint for new users: When selecting the ffmpeg directory, don't select just the parent folder, but select the "bin" folder in the ffmpeg directory.

Complete control over YT downloads, you can get the audio alone if you like, do conversions, keep the original streams, even save complete pages.

Supports Pale Moon, too. Not much left to ask. Well done, thank you!

(wish they could get more Patreon support - we'd enjoy it on all websites, not just YouTube)

I really was frustrated by a bug. The dev noticed it was important to me and helped me out with a new pre-alpha release which fixed things for me. 6/5 stars. I'm treated like a king and I won't forget.

It does not save 100% of comments. For example a youtube video with 1000 comments.

by cg-addons (Developer) on May 14, 2016 ·

If you tried saving comments then you know the option says "Save Comments Viewed, Max 2000" (see 3rd screen shot above). If you are browsing through a video’s comments and wish to save what you have read, CYS will do exactly that…save the comments you have read…up to 2000. It doesn' t claim to do anything else.

Options say something about icon and arrow but there's no icon nowhere on GUI or customization screen so there's no way to "activate" downloading.

edit: I found out the icon is "fixed" (as in: cannot be customized) on the address bar. Which I do not have. At all. Because pentadactyl.

Fix Using Firefox 46 and CYS v5.6.56:

After installing CYS, restart Firefox and then the Icon will be movable. If you enter "Customize" right after installing v5.6.56, it will not be movable.

Please consider supporting the author on Patreon so that he can continue development. I created an account there specifically for this purpose -- it's quick and easy, and definitely worth it for such a useful tool.

This is the best YouTube add-on out there that can download MP4 videos at their native resolution, or MP3 at high bit rate. Very versatile and powerful. I truly hope development can continue as I cannot find a single, or even combination of add-ons that can do what this does.

This is the best Youtube downloader, probably even better than my long time favorite "Youtube video and audio downloader". It's slick and functional. Perfect for usage with "HTML5 everywhere".

However, it makes stupid assumption about ffmpeg location on Linux, it should search folders of standard $PATH or at least make assumption about /usr/bin where all such binaries are. Also it shouldn't silently create folders, especially in non-standard location like ~/Downloads. At least it should assume FF default download folder.
