Issue with new tabs
I have tried various extensions such as 'new tab redirect' in order to have each new tab bring up a site that I have selected. Though none of the new tab extensions seem to work on vivaldi? Everytime I open a new tab, the speed dial keeps coming up instead.

Unfortunately this feature is not implemented. It is still a feature request. You can take a look at this post for a workaround.
