I inadvertently solved this problem while working on another (gksudo - update manager hanging instead of opening the login box).
After I changed the line in the hosts file 127.0.1.1 so the hostname matched the one in /etc/hostname my buttons came back in Firefox. Don't know if any of this will help, as I am new to Ubuntu linux and not really sure what I am doing at times, but it is worth looking at - it worked for me. -- Navigation buttons greyed out https://bugs.launchpad.net/bugs/236518 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
