Comment 3 for bug 634915

There is currently no way for software center to signal to the plugin-installer that package installation has finished, and this is necessary so that Firefox can reload it's plugins. Without that, the user will need to restart Firefox once they know that software-center has finished installing.

apturl does this by just exitting once it's done, and this is easy to pick up in ubufox. We can't do that with software-center...
