It was working fine until two days ago, but suddenly the download conversion feature stopped working.
Please help me resolve this.

「❌ Error

very good

Very useful and easy to work with

Very useful indeed, many thanks!

Working as stated.

works, and doesn't need to open a new tab on another site to download content on YouTube. Thank you for this extension!

Paywall bullshit. There are FAR too many free alternative that work just as well, or better, to be paying for this. The author must be a bit daft.

Suddenly makes you pay to keep downloading videos out of nowhere

there is a limit to how many videos you can download before it pay walls you. 51.

This seems to be one of those that just works. I like that and you will too.

Thank you very much, I really do appreciate, all is good and works! (I asked for help and very quick to answer!)
