With DNT+ enabled and visiting
amd attermpting to click on one of the links under Frequently Asked Questions on the right hand side mid-way down ... such as the "Getting to know the Linksys E4200: link ... it will NOT open. Disabling the DNT+ addon and then restarting FF13. then revisiting the site & again attempting to open the link results in a successfully visited URL.
I've noticed this behavior on other sites as well, but only now did I track it down to DNT+ as being the culprit.
I like DoNotTrackPlus, but this behavior is a game breaker for me.
I hope this helps, and thanks again for your support!
