In Google Analytic, the majority of organic traffic via Firefox browsers to one of our websites suddenly dropped off, and an immediate lift in direct traffic via Firefox browsers appeared.
This trend has continued ever since. I've searched to find Firefox releases that might have affected it (eg. security/cookie settings), but haven't been able to find anything, or talk of this happening to other people, and the anomaly doesn't appear in our other website analytics either...anyone have any ideas?!
The attached GA graphs show Firefox browser versions 21.0 and 22.0, but it's the same story across all versions. (You can also see that I'd also filtered out traffic via IOS 6 and Android 4 operating systems to remove any effect from these known issues).
Thanks for any help that you can offer!
