Video Download Extension Issue (on avast secure browser)

I used to be able to download video for personal use at YouTube with the video download extension (on the Avast secure browser). One day the option to download simply stopped. I still had the extension installed and activated, but the videos no longer popped up with the green download indicator at the top right hand corner of the video. I tried uninstalling and reinstalling the Avast secure browser, to no avail.
