Package: firefox-esr Version: 60.5.0esr-1~deb9u1 Severity: important X-Debbugs-CC: bvan...@mozilla.com
It was noticed that the Debian stretch version (and most likely also the Debian buster) of firefox-esr uses the wrong channel to search for components. As result, the downloaded components don't work with the esr browser and break major parts of the multimedia features of the browser. This was also confirmed by a Mozilla developer https://bugzilla.mozilla.org/show_bug.cgi?id=1524830#c4 The fix is to use MOZ_UPDATE_CHANNEL "esr" and not "default". One place which is affected by it is $ grep app.update.channel /usr/lib/firefox-esr/defaults/pref/channel-prefs.js pref("app.update.channel", "default"); This should be "esr" and not "default".
