This is a minimal install used for running automated browser tests on AWS. As you say, not a particularly representative example, so I'm happy for you to flag it as not a bug.

When interacting with the browser manually it appears to be noticeably sluggish. A large number of these errors were seen in the terminal: (firefox:1489): GConf-WARNING **: Client failed to connect to the D-BUS daemon: //bin/dbus-launch terminated abnormally without any error message (firefox:1489): GConf-WARNING **: Client failed to connect to the D-BUS daemon: //bin/dbus-launch terminated abnormally without any error message (firefox:1489): GConf-WARNING **: Client failed to connect to the D-BUS daemon: //bin/dbus-launch terminated abnormally without any error message (firefox:1489): GConf-WARNING **: Client failed to connect to the D-BUS daemon: //bin/dbus-launch terminated abnormally without any error message Installing the dbus-x11 package resolved these errors and brought performance back to the same level as Firefox 16.02.
