I have to enter a password to get to the site. The site is hosted by Slack. The owner specifically gives permission to download them. But when I added several extensions for video downloading (ant, video downloadhelper, a few others), none of them detected any media files. Is it something I have do with settings, particularly the extensions? Because I did notice that none of the programs I added are showing up in plugins, just in extensions for Firefox. I repeat, it is a flash video. I even downloaded the free version of a standalone software downloader, and when I pasted the url, nothing happened. Any ideas? Thanks in advance
