I have read just about every help article, and tried the suggested fixes, yet, nothing works. The download manager window opens, it only gives me one choice (save) I save, then it say's download complete, but never gives me another window to install and run. I open the plugin page and no windows media plugin is listed, and I can't play an mp3 file. In my program settings I don't have any choices for any file extensions associated with video or audio ( such as wav. mp3..ect...is this common?) except a video and podcast option, for those I chose windows media player as my default. An article in help said some Windows third party download plugins may interfere with firefox, then it list's the plugins. I can't find these plugins, and this particular article is not concise, it's confusing. Perhaps this is where my problem is. I did not reset firefox, and I'm not going to. I've had it for a couple of days, I'm still configuring it.
