The default configuration of the Proxy Settings for Firefox is "No Proxy" as the Bologna network will let you access the internet without a proxy server. However, if you have synchronised your Firefox profile (the "$HOME/.mozilla" directory from a Reading-based system, it could happen that it retains the previous proxy settings, which were necessary for reading.
To configure Firefox correctly you must use the "Edit / Settings" menu option and the search for "Proxy" on this screen do make sure to select "No Proxy"
