I have set up Safari to start blank. However it still always remember where we went previously and has the tabs filled with previously visited web sites. I would like it to stop doing that. It should just show up a blank tab only when started Also is there any hot key to close all tabs except the current one that comes to the fore? I find the screen does not always respond to my finger and I wouldn't like I have to open the tab before I can close it. These would save me some download.
