Comment 7 for bug 408898

You can get my code via my branch: bzr branch lp:~ruben-verweij/libnotify-mozilla/devel. (just type it in a terminal, install bzr if it isn't already)
The maintainer of this plugin is a bit slow to respond and hasn't merged my changes yet. So, until he merges the changes, you can't download the fix in another way.
