How to display pages back in desktop view after testing the mobile view

I tested the mobile view for some pages on my MAC. When I try to get back to the desktop view, I have been directed to the home page (with a desktop view), but the pages that I tested the mobile view with were stayed in mobile view.

I have worked out that this is caused by the cookies: all pages in the site display in desktop view after removing the related cookies.

Please advice how to fix this so that pages can be switched between the 2 views without manually removing cookies every time.
