I know in one of yours settings there is a slider to show the home button but not sure which settings it's at. You need to go through them and scroll down to find the "Show Home Button" slider to show it.

I had this problem and after looking around - to no avail - I finally figured it out. Here are the steps: 1) Right-click on the toolbar - either to the right or left of the URL field 2) Select the "Customize Toolbar" option 3) Several options will be displayed 4) Click and drag the "Home" button to where you want it on the toolbar

You can click "Done" at the bottom-right corner, but it's not required. I just closed the Customize tab and the home button was on all my other open tabs.

Hope this helps someone!
