problem 3 is
probably the modem?
4 is Firefox doing the spinny loady thing instead of showing me the tab that was fully loaded and done five seconds ago before I clicked to something else and back, and 5 is I'm typing way faster than what I'm typing is showing up; both might be symptoms of problem 1, though
and yes, closing Firefox helps, but the flame emoji next to each thermometer reading doesn't go away until the reading drops below 50C, which means now I've closed Firefox, Core 0 and Core 1 are flickering between flame, green check, and red arrow pointing up. and HD0 doesn't care, it's currently at 74C! also, of course, now Firefox is closed.
(everything is backed up except the Jami Gold beat sheet I downloaded today and haven't changed any, so as long as this thing doesn't actually catch on fire, all I'll lose if it fries itself is my open Firefox tabs. and, you know, a full-size, non-touchscreen keyboard…)
