Favorites at side of screen- after new windows 10 update

[Magic cats]

Does anyone know how to reduce the size of the drop down favorites on the side of the screen. It takes up 1/3 of my screen and I can't seem to resize it after the update yesterday.

Thanks for any help you can give me.

Which Browser are you asking about? What is your screen/display resolution setting?

I am using Edge. Everything was fine until the windows update 2 days ago. Before that I could narrow the list now I don't seem to be able to and it is a lot wider on the side of my screen.
