*Good is that I prudently blocked the autoupdate (mainly because of the removed TabMenu flag).
I still don't get it why this feature was removed! Besides that I used the Closed Tab Menu all the time (and until now never Search in Tabs), it is now more complicate:
I have to make more steps to open older closed tabs. And if I open Search in Tabs via the upper right button, I have to move my mouse cursor back to the center of the screen.
