You're welcome- I've been chronically bored lately, so it was nice to have
something do.
Magic Banana covered most of what's worth noting, so I'll just note what else
I can think of:
*It definitely sounds as though the computer might be under a lot of stress,
especially given the mouse. It is somewhat strange though, given the amount
of RAM (it was memory) and the processor, as well as the fact that Windows 10
worked fine.
*Just out of curiosity, do the page jumps ever occur when after a page is
done loading? Firefox sometimes has a habit of shifting around while loading,
at least on GNU/Linux.
