Okay, that doesn't seem to work for my videos, e.g.:


I cleared the cache, started the video, then ran:

'watch ls -l /home/user/.mozilla/firefox/nnnnnnnn.ProfName/Cache/'

but no video shows up there (I see various things that seem to be cache
infrastructure, and a couple of 'Macromedia Flash data files', but the
latter seem to be player files, not video).

Well, I'm using squid anyway, so I'll give this a try.

I, too, wondered about something like this, but I didn't even get as
far as you did ;)
