rhythmbox: Please remove Mozilla plugin
Submitted by Jeremy Bicha
Firefox 53+ doesn't support the Rhythmbox Mozilla plugin any more.
Firefox 60 ESR will be released in May and Firefox 52 ESR will be unsupported in August.
I propose we drop the Rhythmbox Mozilla plugin.
Note that Epiphany still supports NPAPI plugins, but when I mentioned this issue to the Epiphany developer earlier, he seemed ok with dropping Rhythmbox's plugin.
