There was another change with Gmail today that stopped ActiveInbox showing correctly when in the thread list view, and something weird was happening with Firefox 4.0.1 that meant it thinks ActiveInbox is not compatible with it (it was!).
So, to make ActiveInbox work properly in the new Gmail, and the new Firefox, and to improve Pre-Labeling after all your feedback (it no longer adds a code to the end of your emails), I’ve just released 18.104.22.168.
It should update automatically, but as it can take a few days in Firefox, you might want to update it manually from http://www.activeinboxhq.com/install.html.
