Firefox Cache, Preload

I am running a kiosk with Firefox 2.0. The kiosk uses html code to display videos on a website. The videos are hosted remotely on Dreamhost. The videos are FLV files played with the JW player. The user navigates around the kiosk and then clicks to play a desired video in a popup window

Since the videos are hosted remotely, and the bandwith at my location is not great, I am looking to speed up the load time of the videos.

I had this idea to make an HTML page that has all of the videos on it, like this:

<embed src="mediaplayer.swf" width="400" height="400" allowfullscreen="false" allowscriptaccess="always" flashvars="&height=400&width=400&autostart=true&file=/videos/anderson.flv" />
<embed src="mediaplayer.swf" width="400" height="400" allowfullscreen="false" allowscriptaccess="always" flashvars="&height=400&width=400&autostart=true&file=/videos/cabello.flv" />
etc...

I would navigate to this file first, then after it was done, run the kiosk. The idea is that the videos will already be in the cache, and it would be faster because they could play from the cache.

Will this work? I do not know how long Firefox keeps the videos in the cache and also do not know if there is a cache for just the browser session or for each window or if they expire after a certain time period etc....
Do I need to change any Firefox (2.0) settings to get this to work? Or, are there meta cache tags that I should employ?

 There are 17 videos for a total of 11MB.
