It seems to me that the problem is in your Internet bandwith use and not in Firefox. -- firefox bug https://bugs.launchpad.net/bugs/417738 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
