Server Info Pop up Windows

Whenever I join a server, after I have downloaded the maps, etc. and sent in my user info, TF2 will minimize, and several windows will open on firefox displaying the "window" that has the graphics and info of the server I'm joining.  What seems to be happening is TF2 will not open said windows in the "server intro" screen in game, and must do so using a browser.  Anyone else encounter this problem, and possibly have a fix?  This problem not only happens in TF2, but also for other games I've played.

Oooh, an interesting one.  It seems some setting is forcing your game to open the Server MOTDs (which are normally done in-game with Internet Explorer) with firefox.  Did you uninstall Internet Explorer?  I don't think there's any easy-to-get-to setting that would do this, but you would probably know more.  Other than that, I don't know what to suggest, besides submitting a ticket at the steam support center.  Good luck!
