I have just logged on for the day and the Side Bar has changed. It now has an extra layer making it wider which now pushes a highly used website page off the screen which is very annoying because I don't want to reduce it's zoom any more. I use the Side Bar to bookmark various links within this website as shortcuts to navigate it. How do I remove this unwanted extra layer? Please find attached a Snipping Tool file. The unwanted extra layer is the bar down the left showing my Bookmark icon on the top and the Settings icon on the bottom neither of which I want or need and this is causing the extra width to the sidebar which is upsetting my viewing. How do I remove this new bar?
