This plugin is an unofficial game launcher for the popular online-MMORPG Dungeon Fighter Online, which has currently been released to the public by Neople (http://dfoneople.com/). What this plugin does it effectively replace the original launcher which seems to have varying issues for Windows XP users who try to play the game.
It does this by creating temporary batch files in the OS defined %TMP% directory which simulate the launcher by passing the appropriate values from the login page to the game executable itself. No user file manipulation is required, other than the installation of this plugin.
Requirements for this plugin is the game client (DFO) itself, and a nice copy of the latest version of Firefox. Without DFO, this plugin does virtually nothing.
