I have downloaded the youtube downloader that was recommended by firefox, but everytime i go onto youtube the downloader menu does not appear below the the youtube screen. Can you advise me on how to remedy this problem. The downloader was working previously some time ago then just disappeared. I have attached a screenshot to show that the downloader menu isn't showing. Can you inform me how to fix this? Thank You. Tom O'Doherty-Sheldon. [edited]
