I wanted to play this game called DRAGON BALL Z BUDOKAI X on yoyogames.com (http://www.yoyogames.com/games/show/18469# to be specific). I click "Play Now", and a message appears, saying "Sorry! This game has been made Instant Play only by the creator or a moderator. To play this you need to install the ActiveX or Firefox control, please see the help pages for more information." What is ActiveX and Firefox control? Where can I get it?
