Confirmed: Firefox 68.2.0esr-1~deb10u1 Wayland mode DBUS bug Firefox does not start with MOZ_ENABLE_WAYLAND=1 (or old GDK_BACKEND=wayland) Works with --no-remote, but once open can't open URLs from other applications.
MOZ_ENABLE_WAYLAND=1 firefox-esr --no-remote # temp. partial workaround Related upstream bug to consider (along with Benoît Laniel's fix): https://bugzilla.mozilla.org/show_bug.cgi?id=1551664 Thanks
