IPv6 address not detected Rated 2 out of 5 stars
Using this extension on Ubuntu 11.04 64 bit, Firefox 5.0. SixOrNot does not detect the global IPv6 address in case both an A and AAAA is detected for the domain. For IPv6-only sites, this extension behaves as expected.This review is for a previous version of the add-on (0.6.5).
Thanks for your feedback - a fix for Ubuntu is in the works and should be out soon!
