I have now resorted to finding an extension that does work and although I did this exercise the other day without success, I have now installed "Easy YouTube Video Downloader Express 7.20", which does show a more subtle Download button in Green but in a slightly different place on the YouTube Video page, so instead of to the right of Subscribe button, it is underneath. I have, as suggested, sent an email to the developer and if I do receive a response from them, I will post it to this question. I did Disable all other Extensions and restart Firefox, but unfortunately this made no difference, even though it did work originally. Please don't use reviews as a support forum.Thank you for both your messages.
