Size of Bookmarks Folders & Drop Down far top right

My bookmarks at top left & Drop Down at top far right, are very small. Barely visible, i haven’t seen a setting for it. Can barely see the names of the folders, use of magnifier needed.
As for drop down options are small. When i click on settings, the Settings Tab opens in a new Tab, the page is of normal size.

Size of Bookmarks, Customize and Control issue corrected promptly a day after i posted the problem.
