Using Chrome as default browser - Beginner


Please accept my apologies for such a simple question, I am very much a beginner.

I have set Chrome to be my default browser for the HTML course and it is working, but… Whenever I refresh the page updates, but in a new tab. How can I get Chrome to only update in one tab, rather than multiple.

I have looked in the Chrome settings, but cannot see any options to achieve this.

Thank you

how are you refreshing your browser?
I also use Google Chrome to do HTML
