Except for the Mozilla site, my web pages keep loading all of the content on the left side of the page. How do I fix this?
The page pulls up full-screen, but 2/3 of it is white. All of the page content is displayed vertically down the left side of the page, one image or item at a time. How do I correct this? It was working fine when I first downloaded Mozilla yesterday. This happens with all web pages i've tried to view.

Opening in the side bar is the default for bookmarks that are created via a link or button on a website.
You can check the Properties of a bookmark via the right-click context menu in the side bar (Ctrl+B; Cmd+B on Mac).
In the Bookmarks Manager (Bookmarks > Organize Bookmarks) you can click the More button in the Details pane at the bottom right.
Make sure that "Load this bookmark in the side bar" is not selected.
