Just trying again. First thing.
On Startup in Settings, I have changed the Homepage to www.google.com in "Specific Page"
Still comes up with what I assume is Vivaldi default, all the Tiles.
With what you said as Tiles (Speed Dials), was Vivaldi Start Page.
There's many ways to do what you want.
Set "Homepage" in "Startup" settings as www.google.com.
Go to "Tabs" settings, set "New Tab Page" point to Homepage
Of course, you could just set it up only in New Tab Page. There's "Specific page" option too there.
"Homepage" by default only show up when you hit "Home" button or
And also by default, open Vivaldi new tab page.
@dLeon Thanks, Distinction between Homepage and Startup page confused me a little. OK now.
