Add-On No Longer Working Noté 5 sur 5 étoiles

I have used and enjoyed this add-on for quite a while. However, after downloading the most recent update, the Video DownloadHelper button has vanished from the upper left area of the browser.

I have uninstalled/reinstalled the add-on, ensured it's activated, ensured the "show icon" features have been activated, and even uninstalled/reinstalled Firefox.

Also, the quick launch commands are not working, nor is the option appearing when I right click video content.

Please help!!
