Right alongside Firefox's update today, Mozilla has also brought Thunderbird up to the 126.96.36.199 (.188.8.131.52) version with a big improvement for Intel Mac owners: Universal Binary super-powers. Also in this update are security and bug fixes. Let us all take a moment of silence in remembrance of the bugs who lost their lives in the making of this update.
One thing I am not sure of, however, is if that GmailUI extension we blogged earlier will work after this update. Does anyone know?
