Comment 3 for bug 1181851

This issue has continued being there all the time. I have to reload every page several times until I get music properly playing without Firefox offering to download the mp3 file, and it makes UbuntuOne music barely usable.

I noticed that it happens always when I load a page into a new (background) tab.
And for the current (foreground) tab it happens when I click play on the firsttop-most item within < 3s after loading the page. When I wait >= 3s before playing, it works most times.
