yup, yup, yup, yup. not sure i mentioned but one of *my* symptoms
was the excruciatingly long time it took to open a new tab (up to
several seconds), but that's when i had flash enabled. since i turned
it off, things have been much snappier.
however, i just ran "top -o %CPU" and, while firefox is taking
little CPU time, it's now up at RES = 566m.
