GWT: 0.5, Impossible to start a session with Firefox (versions to precise) after the BFM portal update (July 2013)
The message “La session n’a pas pu être démarrée” is displayed when
opening the BFM portal page with some Firefox versions (21,… ) since the
last update (July 2013).
It is necessary to re-initialize Firefox in order to be able to work
with the portal again.
