I am trying to write a method that will open powerpoint doc in the browser while using Firefox browser. I DEACTIVATE the feature "Open Documents in Client Applications by Default" and when I try in manauly it opens the doc in the browser BUT when I try to open the doc in the browser it, for some reason, tries to open it in the Client computer. I must say that I am tried my method while using IE8/9 with success - it open the doc in the browser.

thanks, Asaf
