I thought Fx 10 ESR was not going to restart after installing this update. It took a VERY long time but it did finally restart and everything seems ok. But it doesn't work as well on this version of Fx as it doesn't collapse other trees automatically when a tab gets focus. It works better on Fx 4 on my host machine. Both machines run XP Pro so I don't know why it works better on Fx 4.

On Fx 4, I have not been offered an update (when I check for updates) to Tree Style Tabs since March. I was offered an update to Multiple Tab Handler and Informational Tab but not Tree Style Tabs. The Informational Tab update has made the progress meter very fat. I prefer the more narrow bar which I had until this update. (This was an update available in March but I just got it now for Fx 4).
