How do I get rid of the split screen
I have 2 windows open at the same time. I want to have only one open. What do Ineed to do?
Additional System Details
- User Agent: Mozilla/5.0 (Windows NT 6.1; rv:22.0) Gecko/20100101 Firefox/22.0
Sometimes web pages open in the Firefox sidebar. If you press Ctrl+b, is the left side replaced with Bookmarks -- in that case it's the sidebar -- or does yet a third pane open?
Pages can be directed to the sidebar by a bookmark. If you right-click the bookmark for the problem page and check its properties, you should see a checkbox you can clear.
Does any of that help?
