Removing Manuals and New Tab

Hello,

I use EDGE as my browser. 

For a few days now, I find myself at the top of the screen with a tab titled Manuals. 

and

 at the bottom of the screen a new icon pinned to the taskbar = New Tab / Shift Browser

I do not know what it is. I would like to keep using EDGE that I have always pinned to the taskbar.
