hi mozilla-related packages maintainers, I remember having xpdf blocking access to audio devices several years ago.
I suggest that unless someone can still reproduce the bug in buster (I'm still on stretch, but haven't seen that bug for at least a year or so), that this bug be closed: * this is Debian bug #517256 * first message 2009-02-26; * most recent tag is fixed-upstream 2017-10-16 - https://bugzilla.mozilla.org/show_bug.cgi?id=1406971 - seems to show that the bug was fixed in firefox 58 - and firefox-esr is now at 60.7.2esr-1 in buster=stable. The related bugs 410671, 487781, 496958 should presumably also be closed. Cheers Boud
