It is indeed horrible! Today I've tried accessing blender.org whose name servers do not respond. When using PAC whole browser locks up for ~15s, unfreezes then locks up again.
Switching proxy to manual or direct resolves issue, though browser seems to freeze for almost second every 10-15 seconds while another tab tries to load page for ~1min. This is on Win7 with FF4.0 I guess this can be reproduced by setting up a dns zone with ns records pointing to dead servers (or finding such domain on internet). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/113201 Title: firefox spends lots of time hung -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
