All I get is a blank page.

Remove History For One Site {web link}

Open the History Manager <Control> (Mac=<Command>) <Shift> H. In the search bar, enter the name of the site. Right-click on one of the listings and select Forget About This Site. This should remove all information, including any site settings

This is not reply with my topic. So, I try to test responsive design. When I click responsive design it is a warning message:

Firefox Can’t Open This PageTo protect your security, www.mypage.com will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window.

Can be avoided as I understand this is a security measure.

You mean a warning will vanish if I click inside history: Forget About This Site

Forget About This Site should remove all data about that website (but not any bookmarks). This could clear some issues.
