Firefox has removed Video Download Helper and add-ons manager doesn't allow me to re-install it (message "download failure" when download OK from elswhere)

Skrevet

A few days ago, I noticed that the Video Download Helper button was removed. Using the add-ons manager I tried to re-install it unsuccessfully The message is "Échec du téléchargement. Veuillez vérifier votre connexion" (download failure. Please check your connection). I checked my connection which is perfect ; downloads from other sites are running correctly I tried to download other download helper modules. The only possible one is "Video Downloader professional" which is not easy to use compared to Video Download Helper. Is there a solution to re-install it ?

Hi Fred, Thanks a lot for your advice The automatic FF version update did not propose the 66.0.5 version, but after updating manually using your link, everything is OK now.
