I am finally about to upgrade from old reliable 10.6.8 (Snow Leopard) to Mavericks, but one thing bugs me. In Safari on Snow Leopard I am able to open the "Activity window" and see most video files loading there (however, not certain sits like Hulu). From there, it's an easy option-click to download said video file (usually in the form of an flv Flash Video file). Is there a Safari add-on or something that will bring this ability back to Safari? I know you can enable the Develop Menu via Safari preferences, and then Show Page Resources, but that doesn't seem to show the video files (or at least, I can't find them). Any ideas or suggestions?
