Comment 1 for bug 901114

Some more info after talking to Michael on IRC:

<noodles775> Thanks dpm
 dpm: so Chromium is taking you to the distroseries which it detected from your browser (without checking if the app existed there--bad)
<noodles775> whereas your FF version doesn't tell us the distroseries that you're using, so it defaults to the configured release (again without checking though...). Should be a straight-forward fix.
<dpm> noodles775, you're right, I hadn't realized Chromium also provided the distro series!
