FireFox 3 mplayer plugin

A lot of people has problem with working mplayer plugin for FireFox 3.
I will describe some way's how to install it.
Becouse Firefox prefers the totem-mozilla plugin over mozilla-mplayer, you must remove totem-mozilla if you have installed.
Remove it with:
sudo apt-get remove totem-mozilla

Now install mplayer-plugin with:
sudo apt-get install mozilla-mplayer

If you don't want use a terminal you can use other way.

Go to Applications->Add/Remove..->Write "mplayer plugin" in search label and install the packet with name Mplayer Plugin for Mozilla.

Now restart FireFox and try if works. If don't work read some way's how to fix that.

If you use FireFox-3.0 it would be good if you first upgrade it to the FireFox-3.0.1

Write this line in shell:
cd /usr/lib/firefox/plugins && ls -la

If in the folder isn't and of mplayerplugin* file or there is no symlinking you need to create it.

Write in shell:
sudo ln -s /usr/lib/mozilla/plugins/* .

Now restart firefox and mplayer-plugin should work.

I hope that i was help you.
