i kept firefox 1.5 running for 2 days, with at most 9 tabs. when i opened up a abiword document, the computer started skipping badly. gkrellm showed that i had 1M swap free. i closed abiword, and it was still the same. then i closed firefox, and after some 100% cpu usage, i got 600MB free (490+ ram, rest swap).

any of you guys with the same problem? what does top show for firefox 1.5 mem usage?
