Hello kilps, Thank you for the bug report, I am presuming that this problem does not occur on any other sites other than ones through proxies? Can you please try running firefox in safe mode, you can do this by running firefox from the terminal with the '-safe-mode' flag, this will eliminate any extension incompatibilities.
I can not find any upstream reports on this yet, however I will keep looking. I am also assuming that it doesn't crash, just the UI freezes until the time the page has completed loading? Could you please clarify these points for me. Thanks again, Alex. ** Changed in: firefox (Ubuntu) Importance: Undecided => Medium Assignee: (unassigned) => Alex Latchford Status: Unconfirmed => Needs Info -- Firefox freeze when on certain network - possible proxy problem https://launchpad.net/bugs/98523 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
