One of the best add-ons I've ever used. Sadly, Google has made changes, and it's not working. Let's hope the developer can fix it.

Know it is (quite likely) not the author's fault of not working... and will be waiting for it come back again.

This is the best Firefox addon, I hope it will be working again soon.

Made an account to write this.Until it recently stopped working this was the very best, thank you. Here's hoping you legends get it back there.

What is the best alternative?

I second that on what AddonReviews said. Thank you Dev for all the hard work and support all these while, I'm grateful for this ext. and it has been a great tool.

Keep up the great work there and never give up.

Hopefully, this ext. will come back working again and rise up to the top. The return of the King Add-ons.

To the people ungrateful people who rate 1 star, lighten up!

This add-on has served me perfectly for years now, and I would like to THANK the developer. Recently it has been broken by google/youtube. I made this account specifically to rate this 5 stars and to request that the developer update the add-on so it functions again.

Either way, THANK you for the years of wonderful usage I was able to get from this add-on!

For all you haters out there, instead of rating one star and leaving scathing reviews, how about giving this add-on the FIVE STARS it deserves, and requesting an update???

Rating this add-on 1-star isn't fair to the developer, who is unable to control when youtube/google decides to deliberately break it.

I ask all in the community to please revise your reviews to this end, and give it the 5-stars it deserves for its years of AWESOME service. Thanks!

EDIT: Is there ANYone out there that can restore functionality to this excellent add-on, or offer a work-around? Thanks in advance.

For those wondering why the Ext won't merge. It is reported that large-size video is very likely to be interrupted while downloading, which will fail in starting any follow-up process (including merging) even such download can be continued to finish. So it is suggested to have another ffmpge-based media converter Ext and do the merging manually, which maybe the season those function in early version be cancelled.

the only application that allows me to download private videos from you tube

it works

It is a MUST add-on for FF w/YouTube
