How do you do this? I have already done it for Gnome. Is this a setting I can change in Firefox. I looked all around and can't figure out why it is launching Totem Player. I installed the MPlayer-mozilla plugin and figured that would force it to take over.

Thanks

You need a plugins for firefox to do so.
Try mplayer-plugins.sourceforge.net

As I stated above I think I already did what you suggest. I beleieve it's this.
<code>sudo apt-get install mozilla-mplayer</code>

How to install Multimedia Player (MPlayer) with Plug-in for Mozilla Firefox?

1. Read General Notes
2. Read How to add extra repositories?
3. Read How to install Multimedia Codecs?
4. Read How to install DVD playback capability?
5.

sudo apt-get install mplayer-386
sudo apt-get install mplayer-fonts
sudo apt-get install mozilla-mplayer
sudo cp /etc/mplayer/mplayer.conf /etc/mplayer/mplayer.conf_backup
sudo gedit /etc/mplayer/mplayer.conf

Firstly, mozzilla-mplayer is not what I meant.
I mean using mplayer-plugins (go on freshmeats and find it).
Sencondly, In opera, I can decide which plugins will handle what kind of file, I choose not to let mozilla-player handle wm* file, and let mplayer-plugins open them.
I don't know how to do that in ff put I think you can figure it out.

Thanks. For firefox --> downloads --> plugins and you can uncheck the filetype.
