Page up and page down keys don't work in Firefox (2020); NOT caret browsing

Page up and page down keys usually don't work in the latest version of Firefox. I say 'usually' because they will start working again at (what seems to me) random times. I have NOT activated caret browsing; the arrow keys work when the page up/down keys don't. Page up/down keys work in all other apps and browsers.

In Firefox, it acts as though 'number lock' is activated - while typing this, I tried the 'end' and 'page up' keys and it typed the numbers, even though number lock is definitely not on (if I try it in another app, it doesn't type numbers but acts as page up/down etc.)

Do Ctrl+PageUp and Ctrl+PageDown work when this happens ?

It is possible that some status keys have the wrong state and Firefox sees them as still pressed.

Try to press all the status keys (Shift, Ctrl, Alt, Windows) a few times to see if that helps to recover from this. If it doesn't help then close and restart Firefox or reboot the computer.
