I didn't write the following, but I agree wholeheartedly with every word.
"This works extremely well and the developer is constantly updating this extension to ensure it keeps working despite the constant code changes from Youtube designed to break utilities like this. A truly excellent extension with top tier support. Many thanks Dishita".
Couldn't put it better myself! It's a great extension and one of the few that is constantly being updated to meet the challenges of Youtube. Highly recommended.
