Facebook site centered

Hi: Got latest update for Win 10 Pro, though don't think that's the problem. When I open Facebook is now appears larger in viewing, but is located in the center of the page, with wide blank space to the left. Not appearing as it normally does with item selections to the left margin, and no blank space showing. Did a restore to an earlier date, and the darn configuration of Facebook still appears as a dysfunction. Would like to get it restored to its normal appearance. How? Thanks, Jim S.

What web browser are you using to access Facebook?

Win Edge

Chances are an "update" to Edge is the cause. It may also be a change to Facebook. Have you tried changing whatever is necessary to restore the look in Edge? Have you tried a different web browser?

Have you tried rolling the center mouse wheel while holding down the CTRL key? That zooms it in and out.
