How to change number of Google search results returned

How to change number of Google search results returned Google search engine in Firefox returns 10 results per page. Is there a way to change it (adding &num=30 in address bar doesn't count)?

"On the Google homepage in the top right, go to Settings -> Search Settings (or just Search Settings if you aren't logged in). Scroll down to Number of results per page and change it in the dropdown box.

You should be able to choose from 10,20,30,50 or 100."

"You can change the number of results by:

Going to about:config in the address bar
Accept the warning message
Find the browser.urlbar.maxRichResults option
The default is 10, you can modify to any integer

Tested in Firefox 66.0."
