My pages or windows have split into 2.
Two websites are showing which is dividing the window causing not full view of either. I want to return the screen to view only one window at a time. Not sure this is Firefox's fault or just something I did.

This looks like you may have installed an addon that divides the window.
- Type about:addons in the location bar and press enter
- Make sure Extensions is selected on the left
- Look for an extension that might be causing this
Possible extensions include, but are not limited to:
- Split Browser
- Fox Splitter
- Tile Tabs
- Split Pannel [sic]
- Tile View
- Tricky Frames
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 > 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 side bar" is not selected.
