Take for example winamp from http://www.winamp.com/download/ Mozilla downloads it to c:\Documents & Settings\david\Local Settings\Temp\winamp3_0-full.exe.mp3 and then launches it from there in my default mp3 player as an mp3 file (which it isn't). Fortunately it makes a mistake about the type of file, because if it didn't this would seem to be a fairly major security problem. The downloaded file IS NOT an mp3 file, rather it is an exe file, and I don't have any idea why mozilla treats it as an mp3 file. I don't believe the mime type from the server is wrong. Reproducible: Always Steps to Reproduce: 1. Go to http://www.winamp.com/download/ 2. Click begin download Actual Results: Download begins, saving the file to a place that I did not specify. No requester appears. It also saves it with a .exe.mp3 extension which is incorrect. Expected Results: 1. I would not expect mozilla to save it as an mp3 file. 2. I would expect mozilla to ask me where to save it. 3. I would not expect mozilla to launch it without permission.

Have yoi configured something in edit\preferences\Navigator\Helper apps ? (assigned to application-octet-stream)

If you have application/octet-stream associated with the .mp3 extension, please remove that association and mark this bug duplicate of bug 189598

Yes, somehow this had been added. I'm sure it wasn't me - perhaps it was another family member. *** This bug has been marked as a duplicate of 189598 ***
