open bug in firefox ! Rated 5 out of 5 stars

adding to the review of mr.buerger, which i second,
is an open bug report for this issue but it hasn't seen much attention yet. BTW, someone has asked about it in mozilla support forum:

btw, does it work the same on other audio and video formats including FLV ?

This review is for a previous version of the add-on (0.2.1-signed). 

It does the job Rated 4 out of 5 stars

It switches off all of the options that cause firefox to play media files (mp3s) instead of downloading them. It does this through a toolbar button to turn on/off the config options for media files. That can be useful if you need to change it often. Having it in a preferences window would be preferable to me.

OR, firefox could actually have a reasonable system for managing how file/MIME types are handled so that add-ons like this wouldn't be necessary. Instead of setting the MIME type for audio files to download and have it ignore that completely and open in their own built-in media player unless you dig down to the potentially dangerous about:config settings.
