jOsh and anyone else affected,

We are sorry that we do not always have the capacity to review all reported bugs in a timely manner. You reported this bug over five years ago and there have been many changes in Ubuntu and Firefox since that time.

Do you still see a problem related to the one that was reported? Please let us know if you do.

If we do not hear from anyone this bug report will expire in approximately 60 days time.

Thank you for helping make Ubuntu better.
