I typed in about: cache > under “disk” click on List Cache Entries > then on the page I see Key Data size Fetch count Last Modifed Expires Pinning, under “Expires” some say “Expired Immediately” witch I want to cache it anyway.

A YouTube video was taken down and I still want to see, so I have the URL to the YouTube video and when I type it into Google, Google has a cache of the video page and when I move the slider in the video, I can see the video, however I does not play, it is more of just still images, so I am thinking that if I tell FireFox to ignore “no-cache” header that YouTube has, maybe I can download the video as it it still on YouTube's server.

I looked to see where FireFox stores all files and it seems noting it stored, not even the still images or videos that I have watched before.

If that is possible -- overriding caching headers may require intercepting a new request and modifying them before they reach Firefox -- I don't know whether videos would be cached to disk in a useful form. They are generally sent in small-ish chunks so that the media server can serve the maximum number of viewers with the least bottlenecks. The YouTube player knows to play these chunks one after the next, and video recording/downloading add-ons have code to deal to create a whole video, but I don't think you or I would find it very convenient to put them together.

Yeah, my guess is you won't find it's if not on YouTube. The Google Cache is for site's/page text and images, but I doubt Google ever Cached videos or animated GIFs, etc.

Don't ya miss the old days of YouTube before Big Brother Giggle took it over and downloading the videos were easier?
