Had to do a full OS install and downloaded a new copy of the secure browser. The video downloader isn’t working and the extension is not installed. I reinstalled the browser several times with the same result. Avast support for the browser is non-existant.
Not something I can confirm. Make sure you’re using the latest version.
I just tried it and it works as expected.
