@leocg That sounds like a reasonable desicion. But then the problem is I don't find the option to reactivate the button in the address bar.

Some updates ago the speed dial button has changed its function. It now opens a new tab and shows the speed dials. The speed dials are my default page for new tabs, so the speed dial button for me is nothing else anymore than the new tab button. Before I used it very often. This update meant for me now that one click I really use often has become two clicks: open a new tab, close the other. It is a small thing, but it's really annoying because it happens so often and I always remember my old routine. Would be very happy if some developer had another thaught about it. But, perhaps I am just to blind to find a setting for this?
