On Friday – October 26th, there was a Fx 2.0.0.9 Test Day which means the final release of Fx 2.0.0.9 should be coming out some time this week. I have seen unconfirmed reports that this release date is going to be this Thursday – November 1st. Should have more info soon from the Mozilla Weekly Update meeting.
Update: Beta users release will be coming later today.
