Downloading .FLV files thru "Window-Activity" method in OS X Lion

I used to be able to download a video on YouTube, etc., by going to "Window" and Activity and selecting the largest file, and double-clicking it. I can't seem to do that anymore since I upgraded to Lion. Is there another alternative to this? I used this a lot to save videos from craft sights (tutorials) that I used all the time. Thanks for any help on this. I have tried using the YouTube buttons for this, but they don't work either; plus, not all the videos I download were on YouTube, but other sites as well.

Thanks,

If you use firefox you can download the extension "download helper". This will allow you save video files from various sites.

cheers

+1 on DownloadHelper. Been using it for years.
