On the Firefox issue: https://bugzilla.mozilla.org/show_bug.cgi?id=1640535
> There is now quite a lot of input delay. Touch-typists typing with one hand on each keyboard will easily out-pace Firefox's ability to display what they are typing. The problem persists until Firefox is restarted. That is exactly what's happening to me, and it looks like it's their bug.
