slow/jerking scrolling in Firefox for MAC

more options

Firefox is frustrating as when on a web page, scrolling up and down is slow to respond and moves in stages. A scroll can be instigated but nothing happens and then it jumps a bit.

Sometimes it seems Ok but this never lasts. A new update is ready to install, maybe that will fix it
