If Firefox does not find Chromium in the Import wizard, create a symlink from ~/.config/chromium to /.config/google-chrome. Then Chrome and Chromium should appear in the Import wizard window. Select Chromium, what type of data to import and it should work.

MPD should use the 3.5mm jack.

Detect if ClickOnce is (or rather: might be) supported by the browser.
This is partly based on https://gist.github.com/adunkman/2371101.
If the userAgent string does not contain a .NET feature hint,
we settle for everything that looks like an IE, because .NET 
is installed nearly everywhere nowadays.

It might also be a good idea to check for the X-ClickOnceSupport 
header on the server side.
