here are a couple of dialog boxes....

they are random and sometimes i have numerous dialog boxes, other times firefox work fine. when the dialog boxes come up i have to click on my pad nuemerous times to get to the next whatever i want....

hi, these are the context menus you get when right-clicking on various elements - maybe your mouse is faulty and registering a left-click as a right-click instead?

i wish that was it but it only seems to do it in firefox, not edge. and i've had this happen on other computer's i've owned.

drive me nuts

can you try to replicate this behaviour when you launch firefox in safe mode once? if not, maybe an addon is interfering here...
