For Firefox, u can find the videos but u'll hv to do a bit of hunting around. Go to the folowing folder:
Code:
C:\Documents and Settings\<user name>\Local Settings\Application Data\Mozilla\Firefox\Profiles\<profile name>.default\Cache
This assumes that Windows is on ur C drive. Now arrange the icons by size. Scroll down to the bottom and u'll see files named like 8E1EC419d01, 23FCBC8Dd01 etc. Ignore files that are named like _CACHE_XXX_. Check files that are of a few MBs in size and copy them to a different folder. Rename them with a .FLV extension and try playing them with a player that supports playback of FLVs.
This is a trial and error method, but works for me.
