PLEASE HELP BEFORE I GO INSANE. Firefox is great with a youtube video download add-on, recently Firefox was asking me to restart with the latest Firefox version 67.01, My youtube downloader was working fine so I put the Firefox restart off till another day and continued for around a week downloading my favourite drummer vids, all was TickaDeeBoo until I decided to go for the latest Firefox 67.01 restart, now my video downloading days are over. I have worked my way through the list of add-on's only to find none of them do the trick. Every time I choose a downloader add-on I click on MP4 360 as it has the audio too, other options are with no audio, no good to anyone. Once clicked, my download destination appears, I click save to store the video in my downloads, in the top right hand corner next to View History & Saved Bookmarks etc is the downward pointing download confirmation arrow which lights up immediately but sadly shows as 0 MegaBytes. Where as when the add-on was working that same downloading arrow would only light up once it had truely downloaded the chosen video. Its really funny you know because about 2months ago I was using an add-on that would only bring up downloading options (MP3,MP4 etc) if you avoided clicking actually on the word "Download", In other words clicking not on the word but away from the word but still inside the box, how weird is that, but it worked everytime, sadly no more. I am a Drummer who follows the lives of my favourite world class Drummers, its great when an add-on works, sound & vision. But when its not working all I can do is record the audio and make do with that. I have been saving in my youtube play list all the video's I've not been able to download in the hope that some day soon that will all change for the better. I sincerely would be over the moon to have this feature back even if its just for a short while (until it all goes pair shaped again) TO THOSE IN THE COMMUNITY, ANY IDEAS ??? Kind Regards, Jonathan.
