Download flash video

In most case, you can use Flash Video Downloader (for Chrome) or other extensions to detect the video url.

In the case browser extensions cannot capture the url, you can open the Developer Tools (in Chrome, press F12) > Reload the page and click to play again the video > Network tab > Media tab > click on any sources on the left column (videoplayback?expire...) > On the right column, in tab Headers > General > Copy the content in Request URL, something like below,

Open a new tab in your browser, Ctrl + S to save the video. You can also open the Downloads manager in your browser (Ctrl + J) to copy the download link and use other Download Manager tools to download this video without using the browser!
