I was able to notice the growth of memory usage in Seamonkey 2.0a1pre rv: 1.9a9pre build 2007101802 in the Task Manager under XP Pro SP2 when using
javascript:alert(setInterval("navigator.plugins.refresh(false);", 2000));
At least 400KB increase in memory allocation after 60 sec.

Can't reproduce on linux. The memory usage goes up a bit first, but then stays
at the same level. And XPCOM_MEM_LEAK_LOG doesn't show any leaks.

Does the memory usage increase constantly on windows?

Using Firefox 3 Beta 2 on Windows XP, Mem Usage went up from 80 MB to 260 MB in one hour. After closing the tab and browsing some more, the Mem Usage did not go down.
