    The disable ipv6 solved my problem of firefox not accessing websites. Good job, thanks. I suspect there are many out there that could use this tidbit of yours.

    Great job, iv been looking for a fix to this problem for a bit. Could do with this info posted on ubuntu problems. :)

    I made these changes with little effect. What finally made Firefox perform as it should was editing the way Firefox connects to the Internet, and checking the “no Proxy” box. That simple change made all the difference.

    Very smart. The changes made a leap. I would appreciate it if you have the time to explain why these changes make that difference.

    Made my day. I couldn’t figure out why XP in a VirtualBox was going so much faster than Firefox on the host. I think it was checking IPv6 DNS timing out then dropping to v4

    Thank you!
