firefox-pgo/plugin-for-mimetype-pref.patch

   1 Description: We introduce a new preference that allows users to set a preferred
   2  plugin for a given mime-type.
   3
   4  For example:
   5
   6   pref ("modules.plugins.mimetype.application/x-shockwave-flash", "/usr/lib/firefox-3.0.1/plugins/libflashplayer.so")
   7
   8  would make the flashplyer installed in that location the preferred one to use.
   9
  10  In case the path is not valid, we just go ahead and search for the first match
  11  given the mime-type.
