I would like very much to have a Speed Dial open up with some other Startup Pages. I do not know what to type in where it says "Add a new page"

For Chrome browser, this is what you place into the "Add a new page" chrome-extension://llaficoajjainaijghjlofdfmbjpebpa/newtab.html .... This will then open up a tab called "FVD Speed Dial"

I'm sure this is as clear as mud lol.....
