Tools/Options/Downloads/ and look at "file types". See if "mid sequence" shows there and double click on it. What action is set to take place when a midi is encountered? It should be set to open in the default location. I have FF 1.06 and midis play just fine. Windows Media Player pops right up and plays them so I know it can be done. BTW, I run XP Pro but you did not mention your OS. What might that be?
The Crescendo 1.5 download page (www.armadilloweb.com) has various versions available for downloading, including: Netscape 7 [XP] and Mozilla 1.4-1.8 [XP]. Both of these use the same download/installation file: ?c51nnt.exe?.
Once this ?c51nnt.exe? file is downloaded and installed on my computer, however, the MIDIs I want played on my personal webpage (the reason I need Crescendo) play in Netscape but not through Firefox 1.0.6 (which I believe is the same as Mozilla?but here I am a bit unsure.
So, anyway, my question is: how can I get MIDIS to play in Firefox 1.0.6? (Note: MIDIs play in IE through Windows Media Player because Windows Media Player is selected as default MIDI player).
