Public bug reported:
When upgrading Firefox from 16.02 to 19, our automated browser tests
took approximately twice the time to complete. 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.
