I had the same problem (not with a ubuntu, but an old Mandriva) and the issue disapeared when I disable the router in my ADSL box ... So something linked to NAT. But I have to note that even with that NAT, it is working in windows. I will try to capture some wireshark traces.
I hop this issue will help to narrow down the issue -- linkedin very slow on Firefox Linux only https://bugs.launchpad.net/bugs/314713 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
