Status: RESOLVED WORKSFORME

(Toolkit :: Downloads API, defect)

Description

[Satish]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0

I have installed Winamp on my system and it is the default application to open
MP3 files (and also RealPlayer). After that I have installed Firefox 1.0.
Recently I have uninstalled both Winamp and RealPlayer.

After this, when I open a link with "mp3" extension in the Firefox browser, it
started downloading the MP3 file to TEMP location. But after 99% it simply
stopped. I think this is because it could not able to launch the default
application to open the .mp3 file.

Reproducible: Always
Steps to Reproduce:
1.
2.
3.



Expected Results:  
It could have asked me to SAVE the file, as it is not able to find the default
application. Probably Firefox did not detect that Winamp and RealPlayer are
uninstalled.

Please reopen it if you have the same problem with the latest nightly build
(http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-trunk/) and the
safe-mode + a clean profile.
