Firefox does support mms

[first007boy]

I have installed
mplayer mplayer-gui mplayerplug-in mplayer-doc mplayer-fonts

but the problem comes

[first007boy]

the mplayerplug-in had already installed,firefox can not play the mms protocol

[friez]

you need the win32codecs for mms

[first007boy]

do you mean all Binary Codec Packages?
I download it and unpack it to the /usr/local/lib/codecs/ & /usr/lib/codecs
all those done,but can not play mms on firefox,only can play mms on shell command

This has nothing to do with codecs. This has to do with associating an application with a protocol. Firefox obviously can't handle that protocol, and it doesn't know what program can. You can TELL firefox which program to launch for URL's with that protocol by going into about:config (in the address bar).

What you want to do is add an entry such as;
network.protocol-handler.app.mms

Give it string type and set value to the executable you want to launch for that protocol.
