When I open some websites (especially social media websites such as Facebook)) they open in a window on the left quarter of the screen. I cannot find any way to get this to open in a full width screen. This problem does not happen to the majority of websites but those that it happens to it always happens.

If you are opening those from a Bookmark, right-click each of those bookmarks and open Properties. Uncheck Load this bookmark in the sidebar.
