파이어폭스 3.0이 이전 버전에 비하여 메모리 관리가 나아졌다고 들었던 것 같은데, 내 환경(Ubuntu 8.10 x86_64와 우분투로부터 제공되는 파이어폭스, 내 선택에 의한 확장기능)에서는 (배불러)죽음으로 달리는 경우가 자주 발생했다.
이런 저런 시도를 해보다가 아래 페이지의 안내를 따라 cache와 sessionhistory를 조정해 봤는데(0으로 :-), 오늘 하루 브라우징은 안정적이다.
참고로, 이런 명령으로 모니터링을 하고 있는데,
$ watch -d 'pmap -x `pidof firefox` |grep " rw"|sort -k2 -r'
메모리가 더 이상 폭주하지 않고 있다. 다행.

Reducing memory usage - Firefox - MozillaZine Knowledge Base
Changing the about:config preferences below may have an effect on memory consumption but may also affect performance or reduce functionality. Read each article for the preference’s effects. Each preference includes an estimate of the amount of memory that can be freed on an average (512MB RAM) system by choosing the most memory-friendly setting.
