Are you using Chrome?
If so, do you mean the page which pops up when you select the Home icon, or the page when you open the browser?
If Chrome, then, in the settings you will see this: (I'm assuming you have the home button on the top screen)
You then click the item I have arrowed, and you will open a screen, where you must type in the url of whatever page you need. In my case (google english/UK) for example, I have
https://www.google.co.uk/#cns=0
For Edge:
When you get to the point where , as you say, there is a plus button, are you first entering an address? (Enter a web address).You don't mention doing so in your post. You must also delete any that are still there, in the line above that entry.
