Stop sidebar opening every time I open Firefox
For a while now, Firefox has been opening with the sidebar appearing every time. I never wanted this and don't know what causes it to open every time I open Firefox browser now.
What setting is there to stop the sidebar automatically displaying/opening upon Firefox startup?
