This is one of the extensions for my browser that I have been using for quite some time and that almost never lets me down.
In my experience, this is not the case with every extension that you find and install at some point.
The creators of this extension have definitely done a good job here. Very good!

works great, easy to use.

fine.

Excellent ! Fonctionne à merveille. Merci !

pls dont

it is very useful for me. I download the tutorial classes from my master's as an mp3 file. then I use an AI to get the transcript and summarize the contents. I don't even need to watch it the tutorial class at all :p

very good

Works some of the time and not other times. The latest foible is dozens and dozens of language options and even though I select English, the language the video was originally recorded, it still downloads in some other language. This developer needs to allow the user to set language preference or at least default to the original language. Goodness, this is not an improvement.
