This extension is great! I have been using it off and on for years.
The problem is YT is constantly changing its codes, so the developer is having to keep on top of the changes, so he can keep the extension working smoothly for everyone.
The problem lies with YT, not the developer, who is always working on a fix for users. So please, if this extension has worked well for you, but one day it doesn't, keep what I have said in mind.
The developer is a one-man show, so please leave positive reviews for him. He deserves them!

This is a great add-on and simpliflies using Youtube. The more they try to keep control you can always find that this add-on is kept up to date. Great service from a one man band

Excellent, saves a lot of time and effort.

this is very good addon. i have downloaded hundreds of videos that helped me to have offline, that could potentialy be taken down. i have bought this extension because i wanted to help the developer keep it up to date, keep it workiing !! i love it and want to have it in the future. so i encourage everyone to suport with money and reviews the addons / apps you love and use !

Used to be good, but it hasn't kept up with Youtube code in over two months. Thanks for the work you did, as a hobby on this, but now it looks like you don't have time for it anymore and it only works on a few videos and only in the Firefox browser. I usually rate 5 stars but it has degraded to 4 and I had to remove it from Edge and Chrome altogether.

Any tool that lets you download video is better than nothing, and this is updated as soon as it's needed. Does the job when needed, so I'm happy.

developer is always working on a fix

perfecto

It is my favorite download add-on for YT

Works like a charm...always best d/l experience.

This works great, the developer makes timely updates to keep it current. Very helpful add-on!
