When clicking lookup, MusicBrainz.org launches in Firefox. My default browser as set in Preferred Applications is Opera.

I built it from bzr source, r944.

Running XFCE (Xubuntu 9.04).

One of the comments says

Is the correct way of opening a browser for Linux - irrespective of desktop - not:

xdg-open http://whatever

As this links the correct handler for gnome / kde / xfce and any XDG compliant desktop.

Here's where I came across it:

I was able to get good response on my system by editing:

/usr/lib/python2.6/site-packages/picard/util/webbrowser2.py

and changing the whole Linux if structure to (as I am on python 2.6):

webbrowser.register('xdg-open', None, webbrowser.BackgroundBrowser(["xdg-open", "%s"]), update_tryorder=-1)
