I've got a question (hopefully super easy) for you smart PC guys who have helped me out so often. I use Firefox both at work and at home. At work I'm using the latest FF on Windows 7. At home, the latest FF on Win10. But at work when I hover my cursor over the buttons at the top of HTF pages ("Tools," for example), the dropdown menus automatically appear. At home, I have to actually click the button to make the drop-down menus appear. Is there some really stupid setting (that I can't find) that would enable my home laptop/Win10/FF combo to drop the drop-down menu with the cursor hovering?
