Please ignore the topic selected above as one of the problems I have is that drop-down lists don't work. Nor can I activate the 3-line action icon top right. The mouse works 100% in all other apps, but not in Firefox where neither mouse button will action a drop-down.

What OS? What version of Firefox?

Try downloading another copy of Firefox and run it from the folder. Do not sign into your Firefox account and see if you have the same issue.
