Hello Turkopticon users,
Six and I have learned from some of you that the very latest Firefox (13.0.1) and Chrome (21.0.1180.57) break the Turkopticon extension. We're working on a fix that should make Turkopticon less brittle when these browser updates happen. It should be available late next week.
If you want to keep using the Turkopticon extension, don't update Firefox or Chrome yet.
We apologize to those of you already hit by this problem.
Lilly and Six
