Everytime I load Firefox, I get a split screen with two sites on it. I have tried the resetting of home page and clicking off the icon to not show the site selection page. I have facebook on the left and it cannot be expanded bigger than a panel. I have a 3/4 screen of what ever web site I wanted to load.

How do I turn this off? Nothing is working and I cannot imagine how it happened.

Can you attach a screenshot?

Use a compressed image type like PNG or JPG to save the screenshot.

Opening in the sidebar 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 sidebar (Ctrl+B; Cmd+B on Mac).
In the Bookmarks Manager (Bookmarks > Show All Bookmarks) you can click the More button in the Details pane at the bottom right.
Make sure that "Load this bookmark in the sidebar" is not selected.

Are you using a bookmark to open the link at the left side that opens in the sidebar?

You will have to check the settings of that bookmark in the Library and click the More button in the right pane to remove the check mark.
