Many years ago in win XP and IE6 we did can set a *.mid music in pages background and play. Why new browsers don't do? the big feature of midi files is tiny size of them. i have searched in google, and midi support is in HTML5 schedule. but the Google Chrome that supports almost all of HTML5, don't play *.mid files. what means?

Hi   !
In Firefox you'd need the QuickTime plugin;   see the article   'Use the QuickTime plugin to play audio and video'     http://mzl.la/1xKrVrv But : Mozilla plans to drop support for all NPAPI plugins (except for Flash) in March 2017, when Firefox version 52 is released.
As for Windows: By default Windows Media Player uses the standard sound device that your system uses. You could post a question on Microsoft support forum though (similar to this support forum)  :

What code is used to play the MIDI files?

Note that you use a 64 bit Firefox version and thus can only use the Shockwave Flash and Silverlight plugins. You would have to install the 32 bit Firefox version to be able to use other plugins like media players. QuickTime in no longer updated and is considered as unsafe and shouldn't be installed.
