Ok, bugs seems to be gone after upgrading the live session with the proposed upgrades for firefox and compiz unity.
This is what I did : - Update packages, in the live session, with the update manager - Logoff from the live session (switch from ubuntu ... in the logout/shutdown menu of the main bar) - Then do an ALT-F1 to switch from gdm to a terminal - issue a : sudo service gdm restart to restart the live session Firefox starts successfully now using the icon in the launcher. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/771334 Title: unity launcher fails to start firefox on liveCD boots about 1/4 boots -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
