Change default app for mp3 in Firefox A little while ago I clicked a link in Firefox that led to an mp3. My thumb slipped and I tapped "always open with",  ES Music Player when what I really wanted was to just save it. Now every mp3 link spawns ES Music Player, and that's not what I want.

How do I reset Firefox so that it asks me again for these kinds of links?

I've already done to "2 finger Top Swipe: Settings: Apps: Firefox: Launch by default: Clear".

ES Music Player isn't in the settings app list at all, so I couldn't clear that.

ES File Explorer, which is the parent app for the music player shows "No defaults set" in Android settings. Internally it has it's own "Settings: Cleanup settings: Clear defaults", but that had no apparent effect either.
This is the setting of Firefox on Android and not android itself
Follow these steps:


Open Firefox and in address bar type "about:config"
Search For "browser.download.preferred.audio/mpeg" (just "mpeg" does the same)
Press on the reset button
From now on, if you download any mp3 file in Firefox, it asks for available apps capable of playing the file. You can again choose once or set it as default.
