I installed "Free Download Manager." I see the plugin in Tools->Add-ons (it doesn't have any options). I use several different flash video downloaders, because I haven't found one that works period on any site. When I save the video with two I tried, they are being downloaded by Firefox's default download manager (which means simultaneously - which is why I installed the download manager - I need them to download one at a time - in a prioritized queue.) [I used to use Flashgot (long ago), and it worked with some download manager I had installed - but over time it failed to see most videos. I installed Flashgot again, and it still fails to see anything but images and video ads.]
Currently, I have to manually start Free Download Manager (from outside of Firefox), start the download in Firefox, stop it, copy the link location from Firefox's download menu, and then add it manually in Free Download Manager. Yuck. Do I need a different download manager (that takes over - recommendations?), or did I somehow install this one wrong or miss a setting somewhere in Firefox?
Thanks for any help.
