as far as i know this only works with Firefox. But it might work with Safari as well.
First go on the website that has the Quicktime video on it.Than click on Tools on the tool bar at the top of the screen, go down and click on the button that says "Page Info". A window with tabs across the top will appear. Click on the tab that says Media, and find the movie. NOTE whenever you do that the video might not come up with its name on the screen, so to find the video, in the scroll box there is a categorie call "type". Find the "embedded" type and click on it. After you do that click "save as" in the same window, now just do whatever you would do if you were downloading anything off the internet, naming and saving the file.
Step 1: Saving the Movie
Click on the Tools button on the top of the page, go down and click on "page info"
Step 2: Get Set Up to Download the Video
A window with tabs will pop up. Click on the Tab marked Media
Step 3: Find the Video and Save It
You look through the page info box until you find the Video you want. After you have found the video you click save as, enter the name you want it saved as, and save it!
There you go i hope you enjoyed my first instructable!
Step 4: Update
If you want to downlaod flash games off, like addicting games or anygaming website. All you have to do is download it like if it was a video like i showed and open it with your internet browser. And the best thing is that, when ever you play it, it will be the full screen.
