When clicking a play button, Firefox sometimes sets the resource path of an mp3 into the address bar and attempts to navigate to it.

This caused a freeze and hard crash in Firefox ~< 20, now it still opens a full-tab totem plugin and plays the mp3. The expected behavior is that the address is always an html page, and the mp3 file is only played by the music player within the page. I didn't find a reproducible pattern, but it happens when clicking for the first time a play button after navigating to that page.
