Lubuntu 13.10 Changes: Firefox, zRAM Added By Default, LightDM Used For The Lock Screen

After an update today, Lubuntu 13.10 Saucy Salamander, the LXDE Ubuntu flavour, has switched to Firefox as the default web browser, replacing Chromium, which is a bit of a surprise, considering that Ubuntu 13.10 may switch from Firefox to Chromium. Other Lubuntu 13.10 changes include the addition of zRAM by default and the removal of Xscreensaver, Lubuntu now using LightDM for the lock screen.
