Windows 10: Drop down menus

My dropdown menus have started opening up with a black background with red lettering. How can I change that back

Pull-down or Drop-down Menu?

I decided to uninstall Firefox after the entries in the Favorites doubled.
(Example: the Yahoo Mail sign-in page appears twice in the list. Deleting
one also deletes the other.)

I have been looking for browsers with pull-down or drop-down menus but
could only find Chrome-styled browsers (without pull-down or drop-down menus).

Would anyone suggest an old style browser?

TIA.

Excel Drop Down Menu Question

I'm toying around with a project for work. We're trying to make an Excel spreadsheet that has a list of parts that employees would sort of use to build an order form. It's coming along nicely and works fairly well with the touch screen tablet we have, but I had a question. At the moment, when you highlight a cell that has a drop down list of choice, a small box with a down triangle appears in the bottom right. You click that, then the list of items appears. Is there anyway I can make it so that when you click the cell the drop down menu appears? This would make working with the spreadsheet on the tablet many times easier.
