k guys, for some reason my firefox refuses to play video clips. all I get is the "Plugin Required" thing (little green puzzle piece). so I click it to install the plugins....and it says "No suitable plugin found" so i click manual install, and install windows media player for the millionth time. and no difference, still can't watch vids. any ideas on what to do? I've reinstalled wmp10 as well as firefox itself. the videos work in IE.
