Firefox: mozilla-media-cache files

Barbara-46
Yes, I did a little searching before posting here, and these files
appear to be mis-behaving, not going away, in most versions of
Firefox.

I was paying no attention, and much to my surprise found in ECS 2.0
boot drive Var->temp->mozilla-media-cache directory about 500MB of
files titled media-cache-1  through ?  I assume they are created when
I view an HTML5 video, and it looks like they hang around forever.  

Clearing cache has no affect.  Do you all just delete these manually?

Yes, they're the HTML5 video file cache and I vaguely remember
discussion around the release of FF4 about how they didn't get cleaned
up correctly. And of course an improper closing such as a crash of FF
will leave them.

Unless you want to save a video, just delete them. They should play in
MPlayer, KMP or vlc if you want to keep a video.

I think there's some cleanup code that only runs on Windows, but should
on OS/2 as well:

That looks doable as long as our idleSvc is good enough and I'm pretty
sure it is as long as Doodles screen saver is running. It's just a
matter of finding time to play with it as right now I'm more interested
in getting newer versions working.
Really eCS should clean up the tmp dir on startup as there are a lot of
things that don't clean up, building anything with configure is bad that
way and currently my solution is to put %TMP% etc on a RAMFS volume,
rebooting cleans it and it speeds up things.
As bug#572579 mentions, enumerating %TMP% with a lot of files is going
to be a performance hit.
