Why doesn't the home button open FVD Speed Dial?

Calab 5 years ago updated 5 years ago 0

Firefox v58.02... FVD speed dial will open when I start the browser, but not when I hit the HOME button. Instead I get a blank page with a Firefox logo in the top left corner. Clicking the logo takes me to a Firefox tour.

The extension is enabled. I'm not sure what I should be doing to make it work.
