@schtekaren Oh, now I understood! So the home button works simply quite like a new tab button! Thank you for the explanation. I was really sure that it would open speed dial in the current tab.
@operamilleson If you want to know something about my interaction with the browser - I was opening a new tab, where I wanted to see the speed dial, but it was not there, so I was pressing the back button, then the tab got closed, then I was going back to the tab list, moving to the leftmost one to see my speed dial and then I could open my page. So it was a very slow dial, as it was so unintuitive for me.
In my opinion, you should just add a new tab button in place of the home button and SD should always appear in this new tab. It's no use for me to have this static page that lets me think that I have more left to read than I have in reality.
