    Remove the browser plugin
    
    The browser plugin is crashy and broken; there are dozens of bugs filed
    against it on Bugzilla and nobody is looking at them. Chrome and Firefox
    have both dropped support for NPAPI plugins. Epiphany still has support,
    but it's hidden behind a gsetting and all the UI to enable it has been
    removed, so very few users would be able to figure out how to enable.
    I've even previously considered blacklisting this plugin in the past due
    to all the crashes.
    
    Since this plugin has not actually worked in any browsers for a long
    time now, time to delete it.
