FireFox had automatically disabled Flash Video Downloader 16.3.8.
Found version 6.3.11 available - when using it for any videos that indicated "Convert" shows FVD Downloader Module needed installing - even though the module was already installed (I have also uninstalled and re-installed the module to be sure).
But any "Convert" video continues to indicate the FVD Downloader Module was required, So the "Convert" download is no longer working despite the installation of the FVD Downloader Module (1.0.8)
It is better that the previous version - when capture didn't work at Retina at all - however it captures 100% resolution - not 200% and it should. I really need crisp sreenshots
