Same for me. In my words: After upgrading from edgy to feisty, my 32-bit mozilla.com firefox stopped working. It returns "Server not found" for every page. I have reinstalled it, and have deleted the profile directory, but it still does not work and it does not print any messages to the command line. No network activity can be seen with tcpdump.
After extensive searching, I've found http://ubuntuforums.org/showthread.php?t=372487 forum. Looks like libnss-mdns is missing from the ia32 packages. -- 32-bit program cannot use network on X86_64 https://launchpad.net/bugs/93000 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
