Opening a page in the Sidebar is the default action for bookmarks that are created via a "Bookmark this Page" link or button on a website. Make sure you use the many "Bookmark this Page" methods that are in Firefox instead.

Right-click that bookmark and select Properties, then un-check the preference for Load this bookmark in the sidebar, and then click Save.
